Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stuffed Smelts
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Clean and dry the smelts thoroughly.
Stuff the smelts with fish forcemeat and sprinkle with salt, pepper, and onion juice.
Place the smelts in a buttered baking dish and cover with buttered paper.
Bake for 8 minutes in a 400°F (200°C) oven.
Sprinkle with buttered crumbs and bake until the crumbs are brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
