In a medium bowl, cream together the butter and Zesta Caster sugar. Beat in the eggs, corn syrup, and lemon zest.
Step 2
In another bowl sift or whisk together the flour, Zesta baking soda, Zesta baking powder, and salt.
Step 3
Add the wet ingredients to the dry and stir together until combined. Refrigerate until ready to use.
Step 4
Roll out the dough on a well-floured surface fairly thin and cut out rounds with a cookie cutter.
Step 5
Place on an ungreased baking sheet and bake at 375°F (190°C) for 8 minutes. Transfer to a wire rack to cool. Once the cookies are cool, place a teaspoon of Zesta strawberry jam onto the bottom of one of the cookies and top with another one.
