Are Lemons Keto?
Absolutely! They're low in carbs and high in fiber. So go ahead and flavor your water or unsweetened tea with the juice of a lemon, or make your favorite Keto lemon dessert.
Not only are they low in carbs, the nutrients in lemons are reportedly linked to being a potential aid in weight loss and digestive issues. They're an excellent source of vitamin C and have other health benefits that you can read more about in this article.
How Many Carbs in Lemons?
There's only 1.4 gram of carbs in lemon juice for 1 tablespoon. This entire recipe uses only ½ cup, making lemon juice a great low carb flavoring option.
Tips to Thicken Lemon Curd
Though this Keto lemon curd recipe is almost impossible to mess up, there're a couple of things that can happen that causes lemon curd to be runny. The key to making it thick is heating it enough during the cooking phase. The eggs and lemon work together when heated to make a custard like texture, so make sure to cook it for all of the 5 minutes.
Depending on your microwave, you may have to cook it for another 30 seconds and whisk again. But understand, when lemon curd is still hot it's going to be loose. It begins to thicken as it chills in the fridge.
