Use freeze-dried raspberries for bright flavor and no extra moisture, crushing them gently so you get both powder for color and small nuggets for pops of fruit; if using frozen or fresh raspberries, blot well and fold in at the end, expecting a softer dough and slightly puffier cookie. Weighing flour prevents a dry, crumbly dough; target 300 g and stop mixing as soon as the flour disappears to keep the shortbread tender. If the dough feels greasy or too soft to scoop cleanly, extend the chill by 10 to 15 minutes. Bake just until set and pale to keep the shortbread melt-in-your-mouth; overbaking makes them hard. For clean white chocolate drizzles, let cookies cool fully and add a teaspoon of oil to keep the chocolate fluid and shiny.
