Overnight rye waffles with pâté, Port jelly and cornichons

1.For rye waffles, mix the buttermilk, flours, baking powder and 1½ tsp sea salt in a bowl just to combine, then scrape down the sides, cover and stand at room temperature (12-24 hours).

2.For duck liver pâté, heat 30gm butter in a large frying pan over medium-high heat, add livers and turn occasionally until browned and cooked medium-rare (2-3 minutes). Deglaze the pan with Port, then tip mixture into a food processor, wipe out pan with paper towels and return to heat. Add oil, shallot, garlic, thyme and speck and sauté until onion is tender (4-5 minutes). Add to liver mixture, then add vinegar, season to taste and process until smooth. Add cream and remaining butter and process to combine. Pass through a fine sieve into a container and refrigerate until beginning to firm (1½-2 hours).

3.For Port jelly, bring port to the boil in a small saucepan over medium-high heat, cook for a minute, then remove from heat, add vinegar and season to taste. Squeeze excess water from gelatine, stir into Port mixture until dissolved, then cool. Pour a little jelly on the pâté, place a couple of small bay leaves on top and refrigerate overnight. Pour remaining jelly mixture into a jar and refrigerate until set (overnight).

4.Beat egg yolks, butter and thyme into waffle batter to just combine, then whisk eggwhites and a pinch of salt in a separate bowl until stiff peaks form (1-2 minutes). Fold into batter and season to taste with freshly ground black pepper. Heat a waffle iron and brush with extra melted butter. Cook waffle batter in batches, according to the manufacturer’s instructions, until golden brown and crisp (4-5 minutes). Serve hot topped with duck liver pâté, extra Port jelly and frisée salad, with cornichons to taste.
