Preheat your oven to 400 F. Line baking sheets with parchment paper.

Step 2

Sift flour, baking powder, and salt then set aside.

Step 3

Blend the lemon zest with the sugar, rubbing it together with your fingers.TIP - Rubbing the lemon zest into the sugar before combining it with the other ingredients helps release the lemon oils while enhancing the flavor.

Step 4

With a mixer, cream the shortening then gradually add the lemon-sugar.

Step 5

Add egg, lemon juice, and water; beat until combined.

Step 6

Add dry ingredients and mix thoroughly. The dough will be looser and stickier than a traditional cookie dough.

Step 7

Drop by level tablespoons (a cookie scoop is perfect!) onto parchment lined baking sheets. Bake for 8-10 minutes.

Step 8

Allow to cool on baking sheet for 5 minutes, then transfer to wire racks to cool completely.

Step 9

Combine all three ingredients in a small bowl and stir until smooth.

Step 10

Use a 1/2-teaspoon measuring spoon to add glaze to the center of each cookie. Use the back of the spoon to gently spread the glaze. Let glaze harden for a couple hours before storing or stacking the cookies.
