Common varieties of avocado

The  most common type on sale in UK is the Hass avocado which is easy for consumers as the thick knobbly skin conveniently goes black as it ripens, The green-skinned Fuerte, with its slightly more refined flavour and lighter texture, is also an excellent fruit, particularly if you want a large avocado

Selecting and storing avocado

When selecting your Hass avocado ripeness can be measured by the colour of the fruit

-  if green, the fruit is unripe. Don’t refrigerate, instead leave in a bowl to ripen
-  once the skin is olive-green it has 2-3 days until it is ready to eat
-  when brown-green the fruit is ripe but firm. This is ideal for dicing or cutting into cubes
-  once dark brown the avocado is quite soft and as such is suitable for mashing or using in dips
-  if the skin has turned black the avocado is overripe and is not suitable for eating

Fuerte  avocado retain their light green colour even when ripe. It’s best to test firmness to determine degree of ripeness. To speed up ripening, place the avocado in a paper bag for a few days at room temperature. Or, keep avocado next to apples or bananas, as both release natural chemicals which help speed the ripening process. Once cut, any unused avocado should be sprinkled with lemon juice to prevent browning and stored in the fridge. If browning occurs simply cut-off and discard

To freeze simply remove the skin then puree the flesh, adding one tablespoon of lemon juice for every two avocado. Place into containers and freeze for up to 5 months
