Lemon curd has a tangy and sweet flavor. Because it is a useful filling, it tastes delicious on almost everything. That is why it is a common creamy spread used in various baked goods like plain waffles, muffins, cupcakes, and cakes.
Grab a bowl and place it over a pot of simmering water on medium heat. Next, make sure the bottom of the bowl does not touch the water surface. As it begins to boil, reduce heat to low to keep the water simmering.
Add the butter and whisk it to the curd till it melts. Continue whisking until the curd is thick enough to hold whisk marks and bubbles appear on the surface.
