Covers with frosting or icing (on a cake), or makes something extremely cold.
From Old French 'glace' (to freeze), combining the word 'ice' (a noun) with the -s ending to make it third-person singular present tense.
When bakers 'ice' a cake, they're using the same freezing principle as the word's origin—coating something with a cold, hard layer that both protects and decorates.
