Place the trivet in Instant Pot and add a cup of water at a time. Carefully place ramekins in the Instant Pot (3 on the bottom forming a triangle and 1 over the top in the center).

Frequently Asked Questions
Lemon custard is a bit lighter in color compared to lemon custard but they both can be used as a topping and filling for baking. Lemon curd has more eggs, sugar, and butter for its consistency whereas custard is made with cornstarch to thicken it.
Because of the balance of proteins and acid from the lemons, it has to be at the right temperature so it does not damage and create clumps from the milk. This will lead to lumpy custard.
We love making this recipe in the Instant Pot or pressure cooker! It’s easy and there’s no need to constantly watch and stir over the stove. Be careful, however, when layering your ramekins. Our tried and true method is three ramekins on the bottom and one on top. If you’re doing more, just make sure to build up the stack like a pyramid so they are stable.
Storing Jars of Lemon Custard
Store lemon custard in an airtight container in the refrigerator for two to three days. It is not the best frozen and can separate. When ready to reheat, slowly warm up over the stove top stirring it slowly on low heat.
