Goats' milk and marbled muffins

Clare and I nurture a fantasy of one day buying some farmland, where we'll build our dream home while I slowly convert most of the land to a nature reserve and Clare grows vegetables and looks after rescued animals. I imagine there would be a few goats, providing all the milk we'd need. However, until yesterday, when we noticed goats' milk in our local Tesco Metro, I had never tried it. It turned out to taste very similar to cows' milk. Today I used some to make Marbled Chocolate Muffins, from 1 mix, 50 muffins.
