Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Browning Coffee
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Inspect the coffee berries, removing any imperfect kernels and grit.
Wash and dry the berries, then place 1 to 2 pounds in a dripping pan.
Preheat the oven to 400°F (200°C).
Roast
Brown the coffee, stirring thoroughly from the outer edges to the center and vice versa.
Aim for a decided brown color, avoiding yellow or very dark shades.
You can also brown the coffee in a skillet on the stove.
Finish and store
Once partially cool, stir in the beaten egg to clarify the coffee.
Alternatively, stir in a small lump of butter while the coffee is still hot.
Grind the coffee to medium fineness as needed, and store it in a tightly covered container.

What each ingredient does
- Coffee berries
- Provide the beans that roast into the coffee flavor, color and aroma.
- Beaten egg
- Optional addition stirred in to clarify the coffee as it cools.
- Butter
- Optional fat stirred into the hot coffee, adding richness to the finished beans.
The step that matters
Aim for a decided brown color. Roasting drives the sugar and protein browning reactions that build coffee flavor. Pale beans taste grassy and sour, while overly dark or yellow-streaked beans taste burnt or uneven. Stirring from edge to center keeps the roast even.
