RIB EYE STEAK WITH BLUE CHEESE COMPOUND BUTTER AND CRISPY ONION STRINGS RECIPE BY TASTY

Steps:

• Make the compound butter: In a medium bowl, mix together the butter, blue cheese, chives, salt, and pepper until well combined.
• Transfer the butter to a piece of plastic wrap and roll into a log. Refrigerate for at least 1 hour, or until ready to use.
• Make the fried onions: In a shallow bowl, combine the onions and buttermilk and let sit at room temperature for 1 hour.
• In a medium bowl, whisk together the flour, paprika, salt, and pepper. Dip the buttermilk-coated onions into the flour mixture, shaking off any excess.
• Fill a large skillet with high sides with the canola oil. Heat the oil over medium-high heat until it reaches 375˚F (190˚C). Once the oil is hot, add the onions in batches and fry for 3 minutes, until golden brown. Transfer the onions to a wire rack to drain and season with salt.
• Generously season the steaks all over with salt and pepper.
• Add the olive oil to a large cast-iron or stainless-steel pan over high heat. Once the oil begins to shimmer, add the steaks and cook, without disturbing, until a brown crust forms, about 7 minutes. Flip the steaks and continue to cook for 7 minutes more, until the steak is browned on both sides. Sear the sides of the steak to render any fat. Add the butter and thyme to the pan. Tilt the pan toward you and baste the steaks with the melted butter for 2 minutes, until the internal temperature reaches 135°F (60°C) for medium rare.
• Serve the steak with the crispy onions and blue cheese compound butter.
• Enjoy!

MY MOTHER'S BUTTER, TOMATO, AND ONION SAUCE

Steps:

• If using fresh tomatoes, peel them. Coarsely chop the fresh or canned tomatoes. Trim both ends of the onion; peel it and cut it in half lengthwise.
• Put the tomatoes, onion, butter, and salt in a 4- to 5-quart saucepan over medium heat. When the tomatoes begin to bubble, lower the heat to a slow but steady simmer. Cook, stirring every 10 to 15 minutes, until the tomatoes are no longer watery and the sauce has reduced, about 45 minutes, depending on the size and shape of the pot. The sauce is done when the butter has separated from the tomatoes and there is no remaining liquid.

RIB-EYE STEAKS WITH GORGONZOLA BUTTER AND CRISPY SWEET ONION RINGS

Steps:

• For gorgonzola butter:
• Preheat oven to 350°F. Place garlic on piece of foil; drizzle with olive oil. Enclose garlic in foil. Bake until garlic is very soft, about 1 hour. Cool. Squeeze garlic cloves out from papery skins into medium bowl; mash garlic with fork. Mix in butter, cheese, and parsley. Season with salt and pepper. Transfer Gorgonzola butter to sheet of plastic wrap. Using plastic wrap as aid, form butter into 1 1/4-inch-diameter log, wrapping plastic tightly around butter. Chill until firm. (Can be made 2 days ahead; keep chilled.) Cut into 1/2-inch-thick rounds.
• For onion rings:
• Pour buttermilk into large bowl. Add onion rings; toss to coat. Let stand 1 hour, tossing occasionally. Mix flour, onion powder, garlic powder, salt, and pepper in another large bowl.
• Preheat oven to 350°F. Pour enough oil into heavy large skillet to reach depth of 3 inches. Heat over medium-high heat to 350°F. Working with a few onion rings at a time, shake off excess buttermilk, then turn onion rings in flour mixture to coat. Fry onion rings until deep golden brown, adjusting heat as necessary for each batch to maintain temperature at 350°F, about 2 minutes. Transfer onion rings to paper towels to drain, then place on baking sheet and keep warm in oven while frying remaining onion rings.
• For steaks:
• Brush steaks with olive oil; sprinkle with salt and pepper. Heat 2 large nonstick skillets over medium-high heat. Add 3 steaks to each skillet and cook to desired doneness, about 4 minutes per side for medium-rare. Serve with Gorgonzola butter and onion rings.

ROAST TURKEY WITH HERB BUTTER AND CARAMELIZED-ONION GRAVY

Steps:

• For gravy base:
• Melt butter in large pot over medium-high heat. Add onions and sauté until deep brown, about 40 minutes. Mix in rosemary and thyme, then flour; stir 1 minute. Add vinegar and honey; simmer until thickened, about 2 minutes. (Can be made 1 day ahead. Cover; chill.)
• For turkey:
• Mix butter and herbs in small bowl. Rinse turkey inside and out; pat dry. Place on rack set in large roasting pan. Sprinkle inside and out with salt and pepper. Starting at neck end, slide hand between skin and breast meat to loosen skin. Spread 1/4 cup herb butter over breast meat under skin. Rub remaining butter over outside of turkey. Place turkey parts and onion quarters in pan around turkey. (Can be prepared 1 day ahead. Cover and chill.)
• Set rack at lowest position in oven and preheat to 350°F. If stuffing turkey, spoon stuffing loosely into main cavity and neck cavity. Tuck wing tips under; tie legs together loosely to hold shape. Roast turkey uncovered 1 hour. Tent turkey breast and tops of drumsticks loosely with foil; roast 1 hour longer. Add 1 cup broth, herb sprigs, and bay leaf to drippings in pan. Continue to roast until thermometer inserted into thickest part of thigh registers 175°F, basting with 3/4 cup broth and pan juices every 30 minutes, about 2 hours 30 minutes longer for unstuffed and 3 hours longer for stuffed. Transfer turkey to platter; let stand 30 minutes (internal temperature will increase 5 to 10 degrees).
• Strain pan juices into 8-cup measuring cup; spoon fat off top. Heat gravy base over medium heat. Whisk in flour, then pan juices. Boil until gravy is reduced to 7 cups, stirring occasionally, about 12 minutes. Season with salt and pepper.

CHEDDAR GORGEOUS! CHEESE AND ONION BREAD AND BUTTER PUDDING

Steps:

• Butter 8 slices of bread and make sandwiches with the grated mature cheese and sliced onion. Cut the the sandwiches into four triangles and arrange them standing up with the points to the top, in a well greased baking dish. (Do NOT use standard American style sandwich bread, it is too thin and will not crisp up!).
• (Feel free to vary to contents of the sandwiches. If it doesn't have to be a vegetarian dish, some ham would be very nice. Or you might want to put some pickle on the sandwiches, some sliced tomatoes, cooked sausage or whatever you fancy.).
• Beat the eggs with the milk, mustard powder, salt, pepper, and the herbs.
• Pre-heat oven to 200C or 400°F.
• Pour the egg custard mixture over the sandwiches. (If you had any cheese left over, sprinkle it on top. Onion, too if you have any left over.) Allow the pudding to stand for about 30 minutes before baking - you get a lighter pudding.
• Bake the bread and butter pudding in the pre-heated oven for about 20 to 30 minutes, or until the cheese custard has set and the cheese on the top is golden.
• In a nutshell - it's cheese sandwiches with savoury custard poured over then baked in the oven - or savoury bread and butter pudding!
• Serve warm for breakfast, brunch, lunch or supper. Can be prepared the night before and baked next morning - bring it to room temperature for about 30 minutes before baking it however.

ROASTED RED ONION WITH THYME AND BUTTER

Steps:

• Try to get 6 equal-sized medium to large red onions. Remove the first layer of skin. With a knife, just take the bottom of the core end of the onion off, to give it a flat base, and make 2 cuts in a cross-shape in the top, cutting half way down (do not cut right through into quarters). Push some chopped or pounded fresh thyme into these gaps with a good pinch of salt (it's important to get the salt right into the gaps) and a little knob of butter. I prefer to cook the onions in an earthenware dish on a thin layer of sea salt or I put them in with my roast chicken or lamb and they cook quite happily in the same tray. Place in the oven fat 200C/400 F/Gas 6 for 30-35 minutes.

• Roughly chop half of the pineapple slices and 1 of the chiles. Put in a food processor with the butter and process until almost smooth. Add 2 of the green onions and the chile de arbol and pulse just to combine. Taste. If the pineapple isn't very sweet, add some honey and pulse just to combine. Transfer to a bowl, cover and refrigerate until firm and the flavors meld, at least 1 hour and up to 24 hours. Let it warm slightly before grilling the fish.
• Finely dice the remaining pineapple and chile. Put them in a bowl with the remaining green onions, the olive oil, lime juice and some salt and pepper. Toss to combine. Set aside while you grill the fish.

Grill, flesh-side down, until charred and you can move it with a fish spatula without the flesh sticking to the grill, about 3 minutes. Flip, and smear some of the pineapple butter on the flesh side. Grill the second side until charred, about 3 minutes.
• Transfer to a platter, smear on a bit more of the butter mixture, top with the pineapple relish and serve immediately.

NEW POTATOES WITH GRILLED ONION BUTTER

• Bring the potatoes to a boil and then cook at a gentle simmer until they test tender when poked with a thin fork, 15 to 20 minutes, though it depends on the size and age of the potatoes. Drain the contents of the pot into a sieve set over a heavy bowl, filling the bowl with the hot water just to warm it. Throw out the water, drop the potatoes in the bowl and cover the bowl tightly with plastic wrap to keep the potatoes warm.
• As the potatoes cook, toss the onions with a little canola oil and salt and pepper and grill over medium-high heat until charred and soft. On the same grill, heat a cast-iron pan. Add the butter and cook until it browns. Remove from the heat, add the rosemary and give the pan a shake; the butter will foam. When it stops sizzling, add the onions to the butter and cook over low heat until they are very tender and the butter has taken on a pronounced oniony flavor.
