On paper, this seems like the food of the future. It produces a massive amount of food per hectare of land. It is rich in vitamins and minerals. It is sturdy and can be shipped great distances without refrigeration. As it grows on trees, there is no need for expensive farm equipment, and no fossil fuels are required for ploughing, planting, and harvesting.
But it is flavourless. Pleasant texture, good mouth feel, easy to chew, but no taste.
That's not enough to adequately describe it. Boiled potatoes or plain white rice have little flavour. Styrofoam has no flavour. Breadfruit has ANTI-flavour. It feels like it is a sponge sucking flavour out of your tongue. If you take a bite of another food at the same time as you have breadfruit in your mouth, there is a net loss of taste. It's like it numbs your taste buds.
The best way I found to prepare it was to simmer it in a rice cooker with some chicken and bacon fat that I had in the freezer. The fat soaked into the breadfruit and seemed to stop its flavour-sponge action. Then it just tasted like chicken. As bland as factory-farmed chicken can be, it's still orders of magnitude more tasty than breadfruit.
If the store still has them, I think I'll get another one, and try drenching it in spices.
