Step 1

Peel the apples. Remove the core and cut the apples into small chunks.

Step 2

Add apples to a saucepan.

Step 3

Then add cinnamon, lemon zest, lemon juice & 1 tbsp water.

Step 4

Stir and bring to a simmer. Cover with a lid and let simmer gently until the apples have softened completely (about 15 minutes).

Step 5

Once the apples have softened, remove the pan from heat.

Step 6

Use a spatula to press the apples through a sieve into another pan. See photos/video for reference.

Step 7

In a small bowl, combine cornstarch with 2 tbsp of water. Stir until cornstarch is fully dissolved to create a slurry.

Step 8

Add the slurry and sugar to the apple mixture. If desired, add vanilla here too. Stir well.

Step 9

Bring the mixture to a gentle simmer. This will thicken the sauce and help it set.

Step 10

Simmer until the curd reaches your desired consistency (in my case, this was 1-2 minutes).

Step 11

Remove from heat and let it cool down slightly, then add butter if desired. Stir the butter through the mixture.
