This can be saved by blending in a blender until creamy again. Alternatively, if it scrambles just slightly, you can strain it through a fine mesh sieve so that the scrambled bits get left behind. Lemon curd can also scramble if it isn't whisked vigorously enough. Be sure to use a large whisk with very firm tines.These Keto-Friendly Lemon Bars Are a Dose of Sunshine
