Everton Toffee

Ingredients

Directions

Make the toffee

Combine sugar, water, golden syrup, and one-third of the butter in a large pan.
Stir continuously until dissolved.
Insert a thermometer and add the cream of tartar.
Boil until it reaches 260°F (127°C).
Add the remaining butter, cut into thin slices.
Stir carefully while boiling until it reaches 300°F (150°C).
Lower the heat and stir gently to prevent scorching.
Remove the pan from heat.
Mix in the essence of lemon and saffron coloring if desired.

Set and store

Pour the mixture onto a buttered marble surface or into a buttered dish, making it half an inch thick.
When it is half cold, score into squares with a knife.
Break into pieces when fully cooled.
Store in a tin lined with parchment paper.

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

What each ingredient does

Butter: Adds fat and richness, giving the toffee a smooth texture and a softer bite.
Granulated sugar: Provides the sweetness and forms the crisp, brittle structure as the mixture cooks.
Golden syrup: Adds sweetness and moisture while helping prevent sugar from crystallising.
Cream of tartar: Acidifies the syrup, helping prevent crystallisation for a smoother toffee.

The step that matters

Stir gently while boiling to 300°F (150°C). Sugar syrup can scorch or burn quickly near the final temperature, and the mixture can also crystallise if stirred too vigorously or disturbed. Gentle stirring and careful heat control keep the toffee smooth and evenly coloured.

Swap the saffron

The recipe marks saffron as optional. How well each one fits the dish's main ingredients (sugar, syrup, butter, cream, lemon):

Cinnamonfits better
Nutmegfits better
Gingerfits about as well
Saffronthe original

Fit is the average pairing score against sugar, syrup, butter, cream, lemon. Candidates are from the same food group and used in at least 100 recipes.
