Lemon Cake Filling is rated 4.5 out of 5 by 17.
Rated 5 out of 5 by from Excellent I have been looking for a good lemon filling or lemon curd/butter to put into a giant cake l am making to feed 600 people at an event. I have been experimenting with heaps of different recipes UNTILL I came across this one last night. Read through all the reviews and thanks to the person who actually put in that she uses 3Tbls of bought lemon juice. I made up a double quantity mix and I was more than delighted with the result. I used my Thermomix to make it and am thrilled to bits that my filling search is over!

Rated 5 out of 5 by from Almost foolproof! I have made this numerous times as directed. In an effort to cut calories and use when I had no lemons, I tried 1/3 cup sugar and 1/3 cup Splenda and 3 tablespoons of bottled lemon juice. Still tastes great! After stirring in the butter/margarine, I always stain the hot filling to remove bits of egg white, cornstarch, and zest if added.

Rated 5 out of 5 by from I really love this filling, as I'm one of those "I'd rather make it, than buy it already made," type person, so I try to do as much as I can homemade. For my process, however, the filling needed to come to a small rolling boil before stirring to allow for proper thickening. I did not have fresh lemon on hand, so I use concentrated lemon juice and about a 1/2 tsp. lemon extract at the end with the butter and it tastes great! Believe me, it's not just good for cakes and cupcakes!!
