Mix dry ingredients (flour through sugar) in a large bowl and add the zest of one lime.
Mix the wet ingredients (egg through vanilla) in a medium bowl and add 2½ tbsp fresh lime juice
Using the very tips of your fingers quickly, or using two forks, cut the ice-cold butter pieces into the dry ingredients until it looks like wet sand.
Add 1/2 cup (a little more or less) white chocolate chips into the dry ingredients and give a quick stir.
Pour the wet ingredients into the dry and stir twice with a large spoon, then add the raspberries. The raspberries will break apart, but that's ok! Don't over mix, or the scones will be hard and tough!
Form the dough into a loose ball and turn it out onto a lightly floured surface.
For large scones, press it into about an 8" flat circle, about 3/4-1" thick. For small scones, split the dough in half and press it into two smaller flat circles, about 3/4" thick. Using a long knife or a bench scraper, cut the circle in half, and continue cutting until you have 10 even-sized, large wedges. (Or if making small scones, cut each smaller disk into about 8 scones each)
*If you don't feel like fussing with a glaze, just brush the tops with a little milk, or an egg wash, and sprinkle on some sugar. Turbinado (raw sugar) works great!
Place them about an inch apart on a parchment-lined cookie sheet, or pizza pan.
Place the scones in the freezer, or fridge while you preheat the oven to 400°. Bake for 20-25 minutes, or until they are lightly browned, or spring back when you press on them. I like mine a little crispy on the outside, so I bake mine closer to 425°.
