Prepare the quails. I took at the rate of 2 quails per person, because the weight of one bird is 150 g (very crumbs).
We will clean the grapefruit and remove the films, they give bitterness. Instead of grapefruit, you can take an orange, it will turn out even tastier, it will give the quail sweetness, unlike the piquancy of grapefruit.
Prepare the garlic and thyme sprigs.
