Grant Achatz’s savoury doughnuts with pine-nut butter

1.Bring milk, butter and 6gm salt to a simmer in a saucepan over medium heat, add flour and beat with a wooden spoon until dough forms a ball and pulls away from the side of pan (1-2 minutes). Transfer to a mixing bowl, add eggs in 3 batches, whisking well between each, and whisk until dough is glossy. Season to taste with black pepper, then fold in parmesan, raisins, capers and lemon rind. Spoon rough balls of 2 tablespoonfuls of mixture onto a tray lined with baking paper and refrigerate until firm (3 hours).

2.For pine-nut butter, process all ingredients and 1½ tsp salt in a food processor or blender, scraping down sides of bowl occasionally, until very smooth (3-4 minutes). Butter will keep refrigerated for up to a week.

3.Heat oil in a large, deep saucepan to 150C and deep-fry doughnuts in batches (be careful, hot oil will spit), turning occasionally, until golden brown (2½-3 minutes; the centres should be creamy, not cooked through like a cake). Drain on paper towels, transfer to a platter and serve drizzled with pine-nut butter.
