- Remove from heat and stir in vanilla extract and a pinch of salt.
Step 3: Assemble the Tart
- Pour the warm filling into the cooled crust.
- Use a spatula to smooth the top evenly.

FAQ
What can I use instead of butterfly pea flower or spirulina for color?
You can omit the color for a natural lime tart or use other plant-based dyes like matcha or beet juice (note it’ll change the color theme).
Can I make this tart nut-free?
Yes! Just ensure your crust ingredients and filling components are nut-free. Coconut is not considered a tree nut by most people, but always check labels.
Is it possible to use lemon instead of lime?
Absolutely. Lemon juice works just as well and creates a brighter yellow tart with a similar tang.
Do I have to bake the crust?
While baking helps it hold together better, you can skip baking and freeze the crust for 15–20 minutes before filling if you prefer a no-bake option.
Can I use another milk besides coconut?
Coconut milk gives the best texture, but oat milk or soy milk can work in a pinch. Just add a tablespoon of vegan butter for added richness.
