Preheat oven to 350 degrees F. Line a 12-cup muffin tin with liners. Set aside.
Zest the lemon, orange and lime into a small bowl and combine well. Set aside. Do not discard the fruit, you'll need them later.
Add the granulated sugar to a large bowl. Mix in half of the citrus zest, using your hands to really combine it into the sugar.
Cut each roll into fourths. Add the pieces, a few at a time, to the citrus sugar and roll around until coated. Place 4 pieces into each muffin tin. Bake for 18-20 minutes, until slightly golden.
While the muffins are baking, mix the glaze. Juice half of the lemon, half of the orange and half of the lime into a small bowl. Add powdered sugar to another bowl. Add 1 1/2 tablespoons of the citrus juice to the powdered sugar and whisk until smooth. Whisk in remaining citrus zest. If the glaze is too thick, add more citrus juice (very little at a time) until the desired consistency has been reached.
Once the muffins come out of the oven, remove them from the tin and drizzle with the glaze. I put the glaze in a ziplock bag and snip a bit of the corner off the bag then drizzle over the muffins.
