How to Tell if a Lisbon Lemon is Ripe
Expert Tips for Perfect Citrus Selection
Determining the ripeness of Lisbon lemons is central to both culinary excellence and nutritional gain. These lemons, distinguished by their moderate size and smooth, yellow skin, are prized for their tartness and minimal seeding. Cultivated widely, Lisbon lemons are a fundamental citrus variety in many kitchens. Identifying a ripe Lisbon lemon involves assessing its color, feel, and fragrance.
