Why it works: Buckwheat and ginger share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and 46 recipes mention both. Both carry 2-heptanol, which smells bitter, floral. The science ↓
The recipe
Ingredients
Contains: wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Preheat the oven to 170 °C (338 °F).
Mix the buckwheat flour, baking powder, and baking soda in a bowl, and set aside.
Mix the maple syrup with the applesauce, lemon juice, and grated ginger.
Make and bake the batter
Mash the bananas with the back of a fork before adding them to the wet mixture.
Combine the dry ingredients with the banana mixture, being careful not to overmix.
Add the dark chocolate and gently mix again.
Line a 20 × 20 cm (8 × 8 in) cake pan with parchment paper and pour the batter into it.
Bake for about 45 minutes, or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buckwheat flour
- Provides the main structure and a nutty, earthy flavour in the cake.
- Bananas
- Add moisture and sweetness, and their starch helps bind the crumb.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Baking soda
- Reacts with the acidic lemon juice and applesauce to help the cake rise.
- Maple syrup
- Adds sweetness and moisture, and helps the crust brown as it bakes.
- Unsweetened applesauce
- Adds moisture and tenderness, partly replacing fat in the batter.
The step that matters
Combine the dry ingredients with the banana mixture without overmixing. Buckwheat flour has no gluten, so overmixing matters less for toughness, but vigorous stirring knocks out the gas from the leavening and can make the cake dense. Mix only until no dry flour streaks remain.

Fit is the average pairing score against buckwheat, flour, maple syrup, ginger, banana, chocolate. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
