Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Nice Sandwich Rolls
Ingredients
Directions
In the evening, make a stiff potato sponge.
In the morning, mix in enough flour to form a soft dough.
Knead the dough well and let it rise until light.
Knead down again, repeating this process two or three times.
Mold into loaves and place in a dripping pan to rise.
Bake carefully for a light brown crust.
After baking, roll the loaves in a damp cloth and let cool for 3-4 hours.
Cut the loaves lengthwise, avoiding the outside piece.
Spread the inside with butter and cut into slices no thicker than ¼ inch.
Layer cold, boiled ham on each slice and roll up carefully.
Serve on an oblong platter, stacked in a pyramid style.
