Tips and Tricks
Tips for juicing and zesting lemons.
To get most juice out of your lemon, roll it on the counter a few times to soften the rind. If it’s been refrigerated, I recommend microwaving the lemon for about 10 seconds.
Use a microplane grater or zesting tool to remove the yellow zest from the peel. Cut the lemon in half and squeeze with a juicer (or by hand) to get out the juice.
Be sure to remove any seeds before adding juice to lemon buttercream frosting.
You’ll need about 2 Tablespoons of freshly squeezed lemon juice. One medium sized lemon should yield that much juice easily.
The heavy cream creates a richer, creamier frosting. However, if needed to, you can substitute milk. Add a little at a time to avoid making the lemon buttercream frosting too thin.
Yes, salted butter will work if you don’t have unsalted. For best results, use a high quality butter with high fat content and low water content.
Keep this frosting in an airtight container in the refrigerator until ready to use. Let it sit out at room temperature for 10 – 20 minutes before using to soften it up.
Freezing is a great option for leftover buttercream! Lemon buttercream can be stored in a freezer bag for up to 3 months. Let it thaw overnight in the fridge and soften at room temperature before adding to your cupcakes and cakes.
