This one is a bit of a disappointment.
From the Sure to Rise cookbook (1895-ish Published as an ad every year)
- 1/2 pound flour
- 1/4 pound butter
- 2 tablespoons sugar
I tried it. It is not up to modern standards. Dry and not sweet. Nothing like the shortbread you have today. I’d add more sugar and make it thicker (that was my mistake).
