Activate yeast: Mix warm milk, 1 tsp sugar, and yeast. Let sit for 10 minutes until foamy.
Make dough: In a bowl, mix flour, sugar, and salt. Add yeast mixture, eggs, butter, vanilla, and zest. Knead until smooth (about 8–10 minutes).
Add fruits: Fold in raisins and orange peel. Cover and let rise for 1–2 hours, until doubled.
Shape & rise again: Place dough in a tall paper mold or loaf pan. Let rise for another 45–60 minutes.
Bake: Preheat oven to 180°C (350°F). Bake for 35–40 minutes or until golden and a skewer comes out clean.
Cool: Let it cool fully before slicing.
