Lemon birthday cake

Today is my mother's birthday so I made a lemon meringue cake! What I did last year was a disaster, because I tried meringue cake for the first time, but yesterday I knew what to do and I succeeded! I adore lemon curd and yesterday I discovered easier recipe than the one I used to follow, you will find lots of recipes in the internet, but what is important you should first warm up eggs with sugar and then add butter with the lemon juice. But be careful! Eggs can be easily cooked!
