Prep the lemons: Zest 1–2 lemons to get 1 tablespoon of zest. Juice enough lemons to yield 1/2 cup of fresh lemon juice.
Strain the juice to remove pulp and seeds.
Blend the base: In a blender, combine almond milk, heavy cream (or coconut cream), lemon juice, zest, sweetener, vanilla, and salt. If using xanthan gum, sprinkle it in while blending to avoid clumps.
Taste and adjust: Lemon intensity and sweetness are personal. Add a bit more sweetener if it’s too tart, or an extra tablespoon of lemon juice if you want more zing.
Strain for smoothness: For an extra-smooth pop, pour the mixture through a fine-mesh strainer into a pitcher.
This step helps remove any undissolved sweetener or zest clumps.
Fill the molds: Pour the mixture into popsicle molds, leaving a little room at the top for expansion. Insert sticks.
Freeze: Freeze for 4–6 hours, or until fully solid. Overnight is best for clean unmolding.
Unmold: Run warm water over the outside of the molds for 10–15 seconds.
Wiggle sticks gently until the pops slide out.
Optional finish: For a “lemon bar” vibe, dust with a tiny pinch of powdered keto sweetener before serving.
