Grab a deep stockpot and line the base with crumpled foil, metal rings, or a small towel so your pudding mold doesn’t hit the bottom. Fill the pot with water, get it boiling, and grease a 1.6-liter mold really well.

Toss the flour, sugar, baking powder, salt, and butter (or suet) into your food processor. Spin it all up until it feels like grainy sand. Move this mixture into a big bowl.

Gently stir milk, zest from the lemon, vanilla, and currants into the dry mixture. Spoon this dough into the buttery pudding mold, snapping the lid on securely.

Pop the mold into the boiling pot. Adjust the water level so it covers halfway up the mold's side. Lower to a gentle simmer and steam for 90 minutes. If using suet, cook up to 3-4 hours for extra fluffiness. Keep an eye on the water level and top it up when needed. Use a plate with weight if the mold floats.

Lift the mold out and let it cool for about 15 minutes. Flip it upside down onto a plate and cut it into slices. Serve warm with some custard drizzled on top.
