Lemons:

Lemon Tart and Bars: 

I love sweets that use lemons because the bitter/sourness from the lemon with the sweetness from the sugar makes a symphony of flavors in my mouth! Lemon bars and a Lemon tart are a good way to use lemon although there are thousands of ways to use lemons in baking but these two ways are my favorites! Here are some recipes for a lemon tart and bars. These recipes are from Jen of Userealbutter.com and they are so yummy and perfect for the spring and summer.
