Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Coats the crumbs and oats so the topping bakes crisp and golden rather than dry.
Rolled oats
Add a chewy, crunchy texture to the crumble topping.
Digestive or ginger biscuits
Crushed, they add a crumbly base texture and a toasty, slightly spiced flavour.
Demerara sugar
Adds sweetness and helps the topping brown and crisp.
Rhubarb
Provides tartness and releases juice that cooks down into the filling.
Frozen raspberries
Add sweetness, acidity and juice that colours and flavours the filling.

The step that matters

Bake until the fruit is bubbling. Rhubarb and raspberries release a lot of juice as they cook. Baking until the filling bubbles and the topping is golden makes the juices thicken and the crumble set, so it is not watery.

Flavor stand-ins for the nuts

How well each one fits the dish's main ingredients (butter, oats, ginger, sugar, cinnamon, rhubarb):

  1. Almondbetter flavor fit
  2. Flaxseedbetter flavor fit
  3. Pecansbetter flavor fit
  4. Nutsthe original

Fit is the average pairing score against butter, oats, ginger, sugar, cinnamon, rhubarb. 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).
