A Wonderleaf question

a real page from the book
Ice cream is made by freezing a sweet cream mixture while stirring it. The churning breaks ice into tiny crystals and folds in air, while fat helps hold everything together. That structure is why it feels creamy instead of hard like a plain block of ice.
The delightful detail is that ice cream is partly a foam. It has frozen water, little air pockets, and fat all sharing space in each spoonful. When the crystals stay small, your tongue feels smoothness; when they grow large, the bite turns icy.
Shake milk, sugar, and vanilla in a sealed bag over ice and salt until it thickens.
Watercolour scenes, straight answers, about three minutes cover to cover.
