Freezing: fast and closest to fresh
Blanched veg like peas, beans, sweetcorn and spinach freeze brilliantly and keep their taste and texture better than any other method. Freezing is quick, needs no special gear, and preserves that fresh-picked flavour when done well.
The trade-off: it runs on your freezer's space and power, and soft fruit and leafy greens don't freeze as well as firm veg.
