How to make a mint and raspberry milkshake

Possible answers:
(a). This should make 2-3 glasses, if you require more add more milk. Add three scoops of vanilla ice cream.;
(b). Once the milk is full or the bottom of the blender has come to a boil, add your other ice cream. Blend again until the mixture is no longer milky.;

(d). Pour 1/2 cup (224 ml) of milk into the blender and process for one minute. Fold in a pinch of salt, and return the blender to the next line.;
The answer is:
(a).
