Shortbread
The classic recipe is 3-2-1. Three parts flour, two parts butter, and one part sugar by weight.
A typical recipe is
300g flour, 200g butter, 100g sugar. Some add a dash of vanilla. Most recommend the butter should be cold.
Most use unsalted sweet butter. Some add a little salt
Process is to cream the butter and sugar, add vanilla or other flavor if any, slowly add flour. Bake at 325 for about 10 mins
Two sticks of butter is 227g. So I've used
sugar 113g
unsalted butter 227g (two sticks)
flour 336g
A little vanilla, a little cardomom powder, to taste
This took 30 mins at 350
From King Arthur and Betty Crocker
1 stick salted butter (227 g) (or unsalted)
3/4 cup sugar (150 g) (or cup of confectioner’s sugar)
Add a capful of vanilla if desired
2 cups (240 g) flour
Blend butter and sugar until smooth. Then work in flour. Add water or butter if it’s too crumbly
Bake 20 mins at 350
Here’s a recipe that claims to be a copycat of Lorna Doone’s
from https://yousaypotatoes.com/lorna-doone-cookies/ accessed 2023/07/28
Other sites say that using both butter and margarine improves the texture as the two fats have different qualities.
¾ cup butter at room temperature
¼ cup margarine
½ cup powdered sugar (60 grams) icing sugar
1 teaspoon vanilla extract
¼ teaspoon salt
1 ½ cups all purpose flour (195 grams) (plain flour)
¼ cup cornstarch (30 grams) (cornflour)
Add the butter, margarine, powdered sugar, vanilla and salt to a mixing bowl and beat with an electric mixer until light and fluffy.
Sift in the flour and cornflour and mix to a crumbly dough. Knead a few times to bring it together, then pat into a disc shape, wrap in plastic wrap and refrigerate for 1 hour (or put in the freezer for 15 minutes) to firm it up slightly.
Preheat the oven to 350°F/180°C and line two cookie sheets with baking parchment paper.
Lightly dust the counter with powdered sugar, then roll out half of the dough to about ¼-inch thick. Cut into square shapes and place each one onto the baking sheet.
Tip: dip the knife into powdered sugar to make cutting easier.
Transfer the Lorna Doone Cookies to a wire rack to cool completely.
