Egg yolks – I talk about why these are so important below. You can’t sub whole eggs.

Heavy cream – this is what gives the ice cream its rich and creamy texture. A ratio of heavy cream to whole milk that I find works well is 2:1. This ensures that the ice cream remains creamy yet light enough to complement the zesty lime flavor.

Whole milk – this lightens the mixture compared to using only heavy cream. A combination of the two offers a balanced creaminess without making the ice cream too dense.

If you’re thinking you want it ultra-rich, so you’ll just use all heavy cream, I wouldn’t recommend it. Ice cream made with only heavy cream and not a mix of cream and milk usually has an odd mouthfeel.

Some people might enjoy it, but I think most people may find it too heavy or cloying. Adding milk can help balance out the richness and create a lighter texture.

Lime juice and zest – you could alternatively use lemon juice and zest if you’d like.

Sugar – no sub here. Liquid sweeteners would make the ice cream too runny and icy. I talk about the possibility of using keto sweeteners below.

Salt – a pinch of salt heightens the other flavors in the ice cream without making it salty. Salt, even when used sparingly, is a subtle yet essential ingredient that supports the overall flavor harmony.



1 – Add yolks & 1/4 cup of sugar to a bowl.

2 – Whisk until the mixture turns a bit lighter.

3 – Add the milk, zest, salt, 1/2 cup of cream and the remaining sugar to a saucepan.

4 – Heat it until steamy.

5 – Pour hot mixture over yolks to temper and return to heat.

6 – On a separate bowl, pour the remaining cream.

7 – Cook the yolk mixture and strain it into the cream bowl.

8 – After letting it cool, add the lime juice & churn.

9 – In this step, you'd put the mixture into an ice cream maker, but if you don't have one, follow the next two steps.

10 – Put it in the freezer until it's halfway into fully hardening.

11 – Take it out to whisk it, to introduce air into it, & put it back into the freezer until it fully hardens.

12 – Enjoy.
