IS LETTUCE A VEGETABLE OR A VEGETABLE?
We often have difficulty in differentiating one from the other, as they are all used in preparing salads. Let’s clear this question up once and for all. According to experts, the difference between vegetables and legumes is in the botanical part of the plants. The parts classified as vegetables consist of leaves (celery, lettuce, cabbage, etc) and flowers (eg broccoli, cauliflower etc), while vegetables are formed by fruits, stems and roots. So you’ve already noticed that our popular lettuce is a vegetable.
If you think that lettuce is all the same, know that there are many varieties of this vegetable, each with its own texture, color and even taste. See how to tell them apart.
Lettuce Americana – With a rounded shape similar to a cabbage, it reacts better to heat, without losing its crunchiness and flavor, which is why it is often used in sandwiches and salads with hot ingredients. Widely consumed in fast food restaurants , it currently holds 30% of the consumer market.
Roman lettuce – Also very popular, it has dark green, long and curly leaves.
Crespa Lettuce – It is the most consumed type, occupying 50% of the market. It is similar in shape to plain lettuce with loose leaves, but with small ripples on top.
Frisada Lettuce – Also known as frisée lettuce , it is a rarer type in the trade. Indicated for salads with strong flavor accompaniments.
Escarole Lettuce – It has a spicy and slightly bitter taste, similar to chicory. Ideal for all types of salad, it goes well with vinaigrette dressing.
The lface Lisa – presents loose leaves and soft texture, slightly wavy. With a mild flavor, it is, together with the crispy and American, among the most consumed varieties of lettuce in the world.
LETTUCE MAKES YOU SLEEPY?
It sounds like a joke, but lettuce is proven to be an ally for those who need a good night’s sleep. That’s because it contains niacin, which helps in the synthesis of serotonin. With a calming and sedative effect, lettuce salad helps to relax, combating insomnia and everyday tensions.
Before buying, make sure the lettuce leaves are very firm, shiny and free of dark areas or insect bites.
When you get home, put the lettuce in the refrigerator, in a plastic frog or in a closed container and remove the leaves as needed.
It is recommended to consume within a maximum of three or four days.
HOW TO WASH LETTUCE
Because it is eaten raw, lettuce requires great care in cleaning, whether to eliminate bacteria or the pesticides used in the cultivation. A good indication is to use Hypochlorite.
See how to do it:
- Remove and discard yellowed, “burnt” or withered leaves.
- Wash the leaves under running water, separating them to eliminate sand, insects or larvae.
- Then fill a bowl with water and add hypochlorite.
- Soak for the recommended time on the package.
- After this time, drain the leaves and arrange them on a clean paper towel or dish towel to remove excess water.
