Dying
for guacamole, but avocados still days from being ripe? Put them in a
paper bag and toss in a banana, apple or citrus fruit.
That's because avocados -- which are powerhouses of ethylene, a
natural ripening hormone -- ripen faster if placed in a paper bag. And
they ripen even faster if you add another ethylene producer, such as a
banana.
Summer is prime season for this increasingly popular fruit. And
while there are nearly 500 varieties of avocados grown around the
world, in North America people tend to favour just a few, mostly Hass
or Hass-like varieties. These avocados are creamy, green-fleshed and
have a pebbly skin that turns purplish-black when ripe.
Hass are your basic guacamole avocados, small and bell-shaped, great
when eaten like a vegetable on salads or, even more creatively,
deep-fried as french fries.
But there are also what are called "green-skinned" avocados, varieties such as Simmonds or Monroe.
These avocados have a smooth skin that remains green when ripe, and
they can weigh up to 3 1/2 pounds (1.5 kg). Green-skinned avocados also
have less fat and more moisture than Hass, giving them a milder flavour.
These qualities make them well suited to sweet preparations, such as
the ice cream favoured by Brazilians or milk shakes enjoyed in the
Philippines. Unfortunately, such avocados are virtually unknown in
Canadian markets.
To tell when avocados are ripe, give them a little squeeze. They
should yield to slight pressure but not be mushy. Unripe avocados
should be stored at room temperature, then moved to the refrigerator
when ripe. They will keep there for two to three days.
To peel, run a knife around the fruit lengthwise, then twist it slightly to separate the halves. Remove the pit with a spoon.
