Why it works: Rye and flour match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,320 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rye Toast
Ingredients
Directions
Prepare the dough
In a bowl, combine rye flour and salt.
Add enough boiling water to form a stiff dough.
Dry the crust by the fire
Place the dough in a buttered pan.
Position the pan in front of a bright fire with a well-raked grate.
As a crust forms, strip it off and keep it hot and dry.
Repeat until you have enough for a dish.
Serve
Break the crust into pieces, dress like cream toast, and serve in a deep dish.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Rye flour
- Forms the bulk of the dough, giving the crust its body and structure.
The step that matters
Stripping the crust as it forms. Removing each crust while it is still thin and dry keeps it crisp. If it stays against the heat too long, the surface can scorch before the interior dries out.
