Why it works: Wheat and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 465 recipes. Both carry hexanal, which smells green, grassy. The science ↓

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.
Prepare
Mix the wheat bran, oat flakes, and corn meal together.
Stir in the molasses and mix with your hands to avoid lumps.
Roast
Place the mixture in a drip pan and put it in a hot oven at 400°F (200°C).
Stir every 5 to 10 minutes for 1½ to 2 hours until it is a nice brown. Be careful not to burn it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wheat bran
- Forms the bulk of the mixture and carries the roasted flavour.
- Oat flakes
- Add body and a toasty, nutty flavour as they brown.
- Corn meal
- Adds a gritty texture and helps the mixture brown evenly.
- Porto rico molasses
- Adds sweetness and colour, and browns further in the oven.
The step that matters
Stirring during roasting. Stirring every 5 to 10 minutes spreads the heat so the bran browns evenly. Sugars in molasses darken quickly and can scorch at high heat, so the mixture must be watched closely to avoid burning.
