In a large measuring jug, combine milk and boiling water.

Add 1 tsp sugar and the yeast, stir gently, and leave in a warm place until foamy.

Prepare the Dough:

In a large bowl, combine flour, remaining sugar, and salt.

Cut in the butter until mixture resembles crumbs.

Beat the egg and add it along with the activated yeast mixture. Mix into a smooth dough.

Turn onto a lightly floured surface and knead 5–10 minutes until springy with tiny bubbles forming underneath.

First Rise:

Place dough back in the bowl, cover, and let rise until doubled in size (about 1 hour).

Shape the Doughnuts:

Divide the dough into 4 pieces.

Roll each piece into a rope 1–1.5 inches wide, then cut into 1-inch strips.

Roll each strip into a ball and place on a tray or wire rack.

Cover lightly and let rise while heating oil to 375°F.

Fry the Doughnuts:
