Avocado

A fruit, not a vegetable

Avocado is a single-seeded drupe — same fruit type as peaches, mangoes, and olives. It’s the only fruit that contains substantial fat (almost all monounsaturated, similar in profile to olive oil). The fat content gives it a creamy texture unlike any other commercial fruit and explains its versatility in both savory and sweet dishes.

A clone empire

Almost every avocado in supermarkets worldwide is a Hass — a single cultivar traced back to a chance seedling in the backyard of Rudolph Hass in La Habra Heights, California, in 1926. Like all named avocado varieties, Hass is propagated by grafting; every Hass tree is genetically identical. The original “mother tree” lived until 2002.

The ripening dance

Avocados don’t ripen on the tree. Once picked, they soften over several days. Squeeze gently — a ripe avocado yields slightly. Speed up ripening by placing in a paper bag with a banana (the ethylene gas accelerates it); slow it down by refrigerating once ripe.

Toast as cultural marker

Avocado on toast has a long history (Australian cafes were serving it in the 1990s) but became a global phenomenon and a generational shorthand in the 2010s. The dish is simple — mashed or sliced avocado, salt, lemon juice, sometimes chili and herbs, on toasted bread — and it’s now on breakfast menus worldwide.
