Not only are they super simple to cook with but they are one of the easiest ingredients to grow too.
Anyone can have a go at growing onions themselves from seeds or sets says John. Here’s how:
• Onion seeds should be sown in trays under glass during the middle of winter. By mid-spring they should be ready to harden off and plant out in rows.
• If you want a fast and efficient way to grow a crop of onions, you should opt for onion sets. These are already specially prepared, ready to plant baby onions that will mature by mid to late summer.
• Plant your onion sets in an open position in a light soil that has been manured during the previous autumn. Leave around 10cm between each one and rows should be around 30cm apart.
• Be sure to keep onion sets weed free. They need very little water, unless it is a particularly dry summer.
• Your onions will be ready for harvesting in the mid to late summer, when the leaves start to turn yellow.
• Once the foliage starts to turn yellow you can lift the onions very slightly out of the ground, so the base of the bulbs are exposed to some sunlight.
• As soon as the foliage has died completely, you can further dry your onions inside a greenhouse or shed before storing them for winter use.
