3 Success Ideas

Although it’s a very easy recipe, listed below are 3 success ideas which have helped me excellent these creamy lemon bars.

  1. Don’t pack the crust in too tight: When urgent the combination into your lined pan, keep away from packing it in too tight. If the crust may be very agency even earlier than baking, think about how dense it is going to be after baking. Press the combination down very evenly along with your fingers or the underside of a measuring cup.
  2. Use a citrus zester: Lemon zest carries plenty of taste within the lemon filling. In case you want a suggestion for a zester, I take advantage of and love (affiliate hyperlink) this zester.
  3. Keep away from over-baking: It may be tough to find out when the bars are achieved, however err on the aspect of under-baking. And understand that the bars will proceed to set as they cool. If over-baked, the crust and edges will likely be fairly agency. As soon as the absolutely assembled bars go within the oven, they take about 23-25 minutes.

And lastly, you want an (affiliate hyperlink) 8-inch pan for these creamy lemon bars. Stretching the recipe right into a 9-inch pan yields very skinny bars, so I don’t suggest that measurement.
