The recipe is somewhat problematic because it gives measurements in both grams and ounces, but the measurements are not equivalent. For example, 1 ounce of butter is not 25 grams. It's more like 50 grams - a difference of about a tablespoon! This actually caused problems for me since I started to measure out ingredients according to principles I am familiar with and ended up going back and measuring everything in grams. Not a big deal, but it was rather annoying. Fortunately, the garibaldis turned out very well and tasted like crunchy little scones. I added 1/2 teaspoon of vanilla to the milk and rubbed the butter into the dry ingredients with my fingers before adding the milk, rather like making pie crust.
