Frequently Asked Questions

- How much does a medium fennel bulb weigh?
- A medium fennel bulb weighs about 300 g, with a small one around 200 g and a large one near 450 g. That range changes the weight of any recipe that counts fennel bulbs by the piece, so set the size selector to match what you actually have before trusting a cup or gram figure.
- How much does an average fennel bulb weigh?
- An average fennel bulb is the same as a medium one: about 300 g. A small fennel bulb is lighter at around 200 g and a large one heavier at about 450 g, so the size you actually have changes the total for any recipe that counts fennel bulbs by the piece rather than by weight.
