This keto no-churn lemon ice cream is based on Martina’s popular No- Churn Vanilla Ice Cream recipe. It’s so creamy and loaded with lemon juice and zest. I used zest of just one lemon for a slightly milder citrus flavour but if you love lemon, feel free to add one or two. Nothing is more refreshing for summer than this.
Add the water, keto-friendly sweetener and lemon peel to a pan. When removing the peel from the lemon ensure you don’t get any white pith or this can make the syrup bitter. Heat on a low heat until the sweetener dissolves and thickens slightly to a syrup, about 7 minutes.
Of course, there’s nothing like gelato made in Italy, but this is our attempt to make lemon gelato at home. With only three ingredients, it’s a simple concept, but does take some time to assemble (mostly hands-off). It’s actually closer to a sorbet made with fruit and water, which is how most of the fruit-flavored gelatos in Italy are made.
Whisk a small amount of hot mixture into egg yolks. Return all to the pan, whisking constantly. Add lemon zest. Cook over low heat until mixture is just thick enough to coat a metal spoon and a thermometer reads at least 160°, stirring constantly. Do not allow to boil. Remove immediately from heat; stir in lemon juice and cream.
