Guavas
Guava fruit, usually 4 to 12 cm long, are round or oval depending on the species. The outer skin may be rough, often with a bitter taste, or soft and sweet. Varying between species, the skin can be any thickness, is usually green before maturity, but becomes yellow, maroon, or green when ripe.
Guava fruit generally have a pronounced and typical fragrance, similar to lemon rind but less sharp. Guava pulp may be sweet or sour, off-white ("white" guavas) to deep pink ("red" guavas), with the seeds in the central pulp of variable number and hardness, again depending on species.
In Pakistan and India, guava fruit is often eaten raw, typically cut into quarters with a pinch of salt and pepper and sometimes cayenne powder/masala. Street vendors often sell guava fruit for a couple of rupees each.
The fruit is also often prepared as a dessert, in fruit salads. In Asia, fresh guava slices are often dipped in preserved prune powder or salt. In India it is often sprinkled with red rock salt, which is very tart.
Because of the high level of pectin, guavas are extensively used to make candies, preserves, jellies, jams, marmalades (Brazilian goiabada), and also for juices and aguas frescas.
Guava juice is very popular in Cuba, Puerto Rico, Colombia, Egypt, Mexico and South Africa.
"Red" guavas can be used as the base of salted products such as sauces, constituting a substitute for tomatoes, especially for those sensitive to the latter's acidity. In Asia, a drink is made from an infusion of guava fruits and leaves. In Brazil, the infusion made with guava tree leaves (chá-de-goiabeira,i.e. "tea" of guava tree leaves) is considered a medicine.
Guavas are often marketed as "superfruits", being rich in vitamins A and C with seeds that are rich in omega-3, omega-6 polyunsaturated fatty acids and especially dietary fiber. A single Apple Guava (P. guajava) fruit contains over four times the amount of vitamin C as a single orange (over 200 mg per 100 g serving) and also has good levels of the dietary minerals, potassium, magnesium, and generally a broad, low-calorie profile of essential nutrients.
