THING TO MAKE WITH SOUR CREAM RECIPES

Steps:

• Whisk ½ cup milk, ⅓ cup flour (42 g), and ½ cup water in a small saucepan until smooth. Cook over medium heat, whisking constantly, until a very stiff paste forms (it should resemble mashed potatoes), about 2 minutes. Remove from heat; scrape tangzhong into the bowl of a stand mixer fitted with the dough hook.
• Gently warm remaining 2 Tbsp. milk in same saucepan over low heat until lukewarm. Remove from heat, add yeast, and whisk until dissolved. Let sit until mixture is foamy, about 5 minutes.
• Add sour cream, sugar, kosher salt, 2 eggs, 4 Tbsp. butter, and remaining 5 cups bread flour (625 g) to tangzhong. Scrape in yeast mixture and mix on low speed until a shaggy dough forms. Increase speed to medium and mix, scraping down sides of bowl occasionally and adding more flour by the tablespoonful if sticky, until dough is smooth and supple, 8–10 minutes.
• Scrape dough onto a work surface and form into a smooth ball; dust lightly with flour. Place inside a clean large bowl and cover with plastic wrap or a silicone lid. Let sit in a warm, draft-free spot until doubled in size, 1–1½ hours.
• Meanwhile, coat a 13x9" pan, preferably metal, with 2 Tbsp. butter (it will be a generous layer, which is what you want). Uncover dough and punch down lightly to expel some of the gas.
• Turn dough out onto a lightly floured surface and stretch into a square.
• Roll out, dusting with more flour as needed to prevent sticking, to a 12" square and sprinkle chives evenly over dough.
• Starting at one end, loosely roll up dough. Flatten with the heel of your hands into a long rectangle. Roll out dough again, dusting with more flour as needed, into a 16x6" rectangle.
• Using a wheel cutter or bench scraper, cut dough into twenty-four 2"-squarish pieces (an 8x3 grid).
• Working with 1 piece of dough, gather all the corners and pinch together to form a teardrop shape. Place seam side down on work surface. Cup your hand over dough and drag across surface, moving your hand in a rapid circular motion, to form dough into a tight ball. Do not add flour, as you want friction between the dough and the surface. Place ball in prepared pan and repeat with remaining pieces of dough, spacing to make a 6x4 grid. Cover pan with plastic wrap and let sit in a warm, draft-free spot until rolls are nearly doubled in size, 45–60 minutes.
• Meanwhile, place a rack in middle of oven; preheat to 375°.
• Using a fork, whisk remaining egg in a small bowl until no streaks remain. Uncover pan and gently brush tops of rolls with egg, then sprinkle with sea salt and pepper. Bake rolls until tops are deep golden brown, 25–30 minutes.
• Remove pan from oven and immediately brush tops with remaining 2 Tbsp. butter. Let cool in pan 5 minutes. Slide a knife or an offset spatula around sides of pan to loosen rolls, then slide a metal spatula underneath to loosen the bottom. Slide entire grid of rolls out and onto a wire rack. Serve warm or let cool.
• Do ahead: Rolls can be formed and arranged in pan 1 day ahead; cover and chill. Let rise at room temperature before baking (this can take up to 3 hours). Rolls can be baked 3 days ahead. Let cool; store airtight at room temperature.

Steps:

• Heat oven to 275 degrees. Heat oil in a large Dutch oven over medium-high heat. Season short ribs on all sides with salt and pepper. Working in batches, sear short ribs on all sides until deeply and evenly browned, 6 to 8 minutes per batch. Transfer browned short ribs to a large plate and continue with remaining ribs.
• Pour off all but 2 tablespoons of remaining fat, leaving the good browned bits behind. Reduce heat to medium, and add garlic, cut side down and cook, undisturbed, until golden brown, about 1 to 2 minutes. Add onion, celery and carrots and season with salt and pepper. Toss to coat and continue to cook until vegetables are softened but not yet browned, about 5 to 10 minutes. Add tomato paste and stir to coat. Continue to cook, stirring occasionally, until tomato paste has started to caramelize a bit on the bottom and up the edges of the pot, about 2 to 3 minutes.
• Add red wine and, using a wooden spoon, scrape up any browned or caramelized bits. Let this simmer 2 to 3 minutes, just to take the edge off and reduce a bit. Stir in beef stock along with thyme. Using tongs, return short ribs to the pot, along with any juices that have accumulated, nestling them in there so that they are submerged (if they are just barely covered, nestle them bone side up so that all the meat is submerged, adding more beef stock or water as necessary to cover). Bring to a simmer, then cover and transfer to oven.
• Cook, undisturbed, until short ribs are meltingly tender and falling off the bone (you should be able to shred the meat with a fork), 3½ to 4 hours.
• Using tongs, remove the ribs from the pot, taking care (for presentation purposes, really) not to let the bone slip out and transfer them to a large plate. (While you could serve the short ribs right out of this pot, the vegetables have all given up their flavor and texture and aren’t worth much now, so feel free to strain the sauce for easier eating.) Scatter parsley, chives and lemon zest over the top of the short ribs. Separate the fat from the sauce, season with salt and pepper and serve alongside.
