4-5tblspjuice from citrususe more or less, until you achieve the perfect drizzling consistency
1/2tsppure vanilla extract
Instructions
preheat oven to 325°. prepare baking sheet by spraying with non stick baking spray or wiping pan down evenly with shortening
Beat together sugars and butter, taking time to scrape down sides of the bowl. Add egg yolks one at a time. Add 3 tablespoons of the zest from the lemons/limes/oranges. Mix salt and flour together gradually add to butter mixture. Dough will be crumbly. Drizzle in 4 tablespoons citrus juice while mixing, scrape down sides of bowl making sure that everything is combined.
Place dough in pan (12x15" pan, baking sheet type with low rim is what I used), lightly flour hands and then press dough evenly in to all corners of the pan.
Bake at 350 degrees for 25 minutes. Allow to cool for 5 minutes in pan, then flip bars out on to parchment paper. You will have to make a quick flip of the pan to do this so the bars don't break in half. I suggest covering with parchment paper and using a large cutting board place this over top of baking sheet covered with parchment and then do a quick flip so it all lands on the cutting board. Allow to cool.
Whisk glaze together and drizzle glaze over top of bars, and sprinkle with the remaining citrus zest. Cut into squares, store in an airtight container.
