If the cakes and fishes are hard to find then a grocer may stock the very fine long pasta called angel hair (or angel’s hair, as it says in my Collins dictionary, the hair apparently all coming from one single and astonishingly hirsute angel).
If you want to see a real with-wings type angel, then angelology (yes, I'm afraid that really is a word) suggests that there are many types available for spotting, namely seraphim, cherabim, thrones, dominions, virtues, powers, principalities, archangels, and angels.
If all else fails, I suggest in this season of goodwill (ha!) being an angel yourself and making someone a much-needed cup of tea.

Spot the Frippet: angel. This word comes from the Greek angelos, which means messenger.
