BEST OIL FOR FRYING DOUGHNUTS RECIPES

Steps:

• Whisk together the flour, granulated sugar, baking powder, 1 1/4 teaspoons of the salt and the nutmeg in a large bowl until completely combined. Whisk together 2/3 cup of the buttermilk, the sour cream, eggs, yolks, 1 tablespoon of the vanilla paste and the oil in a medium bowl until completely combined. Fold the wet ingredients to the dry ingredients just until a soft and sticky dough comes together (do not overwork).
• Line a rimmed baking sheet with parchment paper and liberally dust with flour (about 1/3 cup).
• Scrape the dough onto the prepared baking sheet. Dust your hands and the top of the dough with more flour, then gently pat the dough to 3/4-inch thick.   
• Working on the baking sheet, punch out as many rounds as you can with a 3 1/4-inch cutter. Then use a 1 1/4-inch cutter to punch out the center of each round. Dip the cutters in flour before each cut to avoid sticking. Gather the dough scraps and gently re-roll without overworking the dough. Repeat cutting until all the dough has been used (you should have 8 doughnuts).  
• Set a wire rack inside a rimmed baking sheet and line a second rimmed baking sheet with several layers of paper towels. Fit a large heavy pot with a deep-fry thermometer and pour in oil to a depth of 3 inches. Heat over medium-high until the thermometer registers 375 degrees F.   
• Fry the doughnuts in batches until deep golden brown, about 2 minutes per side. Transfer to the wire rack and let cool slightly. Fry the doughnut holes until deep golden brown, about 90 seconds per side. Transfer to the wire rack and let drain for 1 minute. Then transfer to the paper-towel lined baking sheet to cool for 10 minutes before glazing. (This two-step process gets a lot more oil out of the doughnuts than using only one method.) Repeat with the remaining dough, making sure the oil returns to temperature between batches.    
• Whisk together the confectioners' sugar, the remaining 6 tablespoons buttermilk, the remaining 1 teaspoon vanilla paste and 1/8 teaspoon salt in a medium bowl until the glaze is smooth and the consistency of honey; add more confectioners' sugar or buttermilk if necessary.   
• Dip each doughnut into the glaze on one side (we like the craggy side, it has more texture for an appetizing appearance), letting the excess drip back into the bowl, then return it to the wire rack. Toss the doughnut holes in the glaze to coat completely and return to the wire rack. Let the glaze set for 10 minutes before serving.   

Steps:

• Put 150g water and all the dough ingredients, apart from the butter, into the bowl of a mixer with a beater paddle. Mix on a medium speed for 8 mins or until the dough starts coming away from the sides and forms a ball. Turn off the mixer and let the dough rest for 1 min.
• Start the mixer up again on a medium speed and slowly add the butter to the dough – about 25g at a time. Once it's all incorporated, mix on high speed for 5 mins until the dough is glossy, smooth and very elastic when pulled.
• Cover the bowl with cling film or a clean tea towel and leave to prove until it's doubled in size. Knock back the dough in the bowl briefly, then re-cover and put in the fridge to chill overnight.
• The next day, take the dough out of the fridge and cut it into 50g pieces (you should get about 20).
• Roll the dough pieces into smooth, tight buns and place them on a floured baking tray, leaving plenty of room between them, as you don’t want them to stick together while they prove.
• Cover loosely with cling film and leave for 4 hrs or until doubled in size. Fill your deep-fat fryer or heavy-based saucepan halfway with oil. Heat the oil to 180C. Read our guide on how to deep-fry safely for more essential information.
• When the oil is heated, carefully slide the doughnuts from the tray using a floured pastry scraper. Taking care not to deflate them, put them into the oil. Do 2-3 per batch, depending on the size of your fryer or pan.
• Fry for 2 mins each side until golden brown – they puff up and float, so you may need to gently push them down after about 1 min to help them colour evenly.
• Remove the doughnuts from the fryer and place them on kitchen paper.
• Toss the doughnuts in a bowl of caster sugar while still warm. Repeat the steps until all the doughnuts are fried, but keep checking the oil temperature is correct – if it's too high, they will burn and be raw in the middle; if it's too low, the oil will be absorbed into the doughnuts and they will become greasy. Set aside to cool before filling.
• To fill the doughnuts, make a hole with a small knife in the crease of each one, anywhere around the white line between the fried top and bottom.
• Fill a piping bag with jam and pipe into the doughnut until nicely swollen – about 1 tbsp per doughnut. After filling, the doughnuts are best eaten straight away, but will keep in an airtight tin.
