    Tips for Usage Cooking and Eating

    Guava is a nutritious fruit with edible seeds and skin. Several varieties are available with each variety having a unique flavour and aroma. Before proceeding to eat guavas, it is necessary to wash them in cold running water to remove any dust and insecticide residues. The floral ends and remnants i.e. sepals should be removed and the tips ends should be cut with a sharp knife. Guavas can then be cubed or sliced like an apple. Guavas should be eaten with their skin on as the edible rind contains abundant amounts of vitamin C. Even the seeds can be eaten; and are very tasty and crunchy. Besides being eaten raw, guavas are often cooked to eliminate their strong odour as some people do not like it.
