Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and 41,516 recipes mention both. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Dixie Potatoes
Ingredients
Directions
Boil three large sweet potatoes until almost tender; remove skins and cut in inch slices. Butter a baking dish and alternate the layers of potato with layers of butter and sugar. Use plenty of butter; add half a cup of water and bake slowly, covered, until the potatoes absorb the syrup, then uncover and brown them nicely.
Look over a peck of spinach and wash through four waters; boil in a saucepan without water for thirty minutes, closely covered. Drain ; rub through a colander. In a skillet put one tablespoonful of butter, and when hot add a teaspoonful of finely-chopped onion; let the onion turn color and add the spinach. Season with salt and pepper, and just before taking from the fire put in three tablespoonfuls of rich cream. Serve on thin slices of toast with hard- boiled egg sliced over the top.
