Melon with lemon Melon-lemon contains twice as muchmore than a regular melon - 700-800 mg per 100 g of product. The acidity level (ph) is 4.5, as opposed to 6.5 for a regular melon. Amazingly unexpected taste sensations, admit tasters who have tried the Spanish hybrid, - to bite into the pulp of a juicy honeydew melon and feel the piquant zest taste. The lemon melon will cost $ 4 per piece. Source: Culinary Eden.
