Ingredients
Directions
Prepare
Blanch and dry the nuts, then chop them into moderate-sized pieces.
Make the nougat
In an enamelled pan, combine the sugar and lemon juice, and melt over low heat.
Once dissolved, add the chopped nuts and stir rapidly.
Pour the mixture into a buttered pan and press into cakes with a buttered knife as it cools.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Castor sugar
- Melts to form the caramel that sets the nougat into a firm, brittle base.
- Chopped nuts
- Provide body, crunch and flavour that hold the set mass together in pieces.
- Lemon juice
- Adds a little acidity that helps keep the melted sugar from crystallising.
The step that matters
Melting the sugar over low heat. Sugar melted too fast or too hot can scorch or darken unevenly before it dissolves fully. Low, gentle heat lets the sugar dissolve evenly so the mixture sets smoothly and does not turn bitter.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, lemon):
- Chickpeafits better
- Pistachiofits better
- Milletfits better
- Nutsthe original
Fit is the average pairing score against sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
