Smoothies

A short shelf, honestly labelled. Every smoothie here is weighed in grams and blended whole, with a full nutrition panel computed from USDA per-100-gram data rather than copied from a carton.

The green protein smoothie builds on whey and collagen under kale, banana, and three kinds of seed. The strawberry banana is a documented classic with chia and warm spices, traced to furaneol for the strawberry and isoamyl acetate for the ripe banana.

The shelf grows from here, and every recipe that joins it arrives the same way: measured, sourced, and traced to its compounds.

Pinch your nose, bite a strawberry, and the strawberry goes away. What is left is sweet and slightly sour, and that is all your tongue was ever contributing. The rest was smell, arriving at your nose from inside your mouth. The famous number attached to this, that 80 per cent of taste is really smell, turns out to descend from six people tasting one ester in sugar water in 1977.
