Quince and vanilla sufganiyot

1.For quince and vanilla jelly, wash quinces, remove fur, then coarsely chop and combine in a large saucepan with lemon juice, seeds and 2 litres cold water. Bring to the boil over high heat, reduce to medium and cook until quince is very pulpy (40-45 minutes). Transfer to a large muslin-lined sieve placed over a bowl, refrigerate overnight to drain (do not squeeze or jelly will be cloudy), discard pulp. Measure quince liquid into a clean saucepan. For every 310ml liquid, add 250gm white sugar. Stir over medium-high heat until sugar dissolves, add vanilla bean and seeds and boil until mixture reaches setting point (4-5 minutes; see note). Remove vanilla bean, transfer to sterilised jars, stand until set (2-3 hours). Makes about 300ml and will keep refrigerated for 6 months.

2.Combine yeast and 80ml lukewarm water in the bowl of an electric mixer fitted with a dough hook, stirring to dissolve, then add caster sugar and stand until foamy (4-5 minutes). Sift together flour, spices and a pinch of fine salt. Add milk and yolks to yeast mixture, mix to combine, then add flour mixture, butter and lemon rind. Beat until smooth, sticky and slightly elastic (4-5 minutes), then transfer to a lightly buttered bowl, turn to coat and cover with plastic wrap. Stand in a warm place until doubled in size (1-1½ hours).

3.Turn dough onto a lightly floured surface, roll to 5mm thick, then cut out 6cm-diameter circles with a well-floured round cutter. Re-roll and cut scraps. Place 1 tsp quince and vanilla jelly in the centre of half the circles, brush edges with eggwhite, top with remaining dough circles, pinch edges to seal. Place on a lightly floured tray, cover, and stand in a warm place until risen slightly (25-30 minutes).

4.Meanwhile, preheat oil in a deep-fryer or deep-sided saucepan to 170C. Deep-fry sufganiyot, in batches, turning often, until golden brown and cooked through (5-6 minutes; be careful as hot oil may spit). Drain on absorbent paper, dust heavily with icing sugar and serve hot.
