Why your backyard citrus is better than anything you will find at the supermarket
In short: Supermarket citrus is often harvested early to survive shipping, but fruit does not ripen once picked. To get the best flavor, you must master the art of touch-picking. By understanding the specific cues for each variety, you can harvest fruit at its peak sweetness and juiciness right from your tree.
The most critical rule of citrus harvesting is that the fruit does not mature or ripen after it is removed from the tree. While skin color may change post-harvest, the internal sugar levels and texture are locked in the moment you pick it. Retailers often prioritize appearance and durability, selling underripe, bright green limes that lack the juice and sweetness of a backyard-grown specimen.
To determine if an orange is ready, use 'touch picking.' A mature orange will feel supple and have a slight 'give' when squeezed. If the fruit feels hard, it is likely immature and may suffer from granulation—a dry, flavorless condition. As the fruit matures, the skin thins, signaling that it has developed sufficient sweetness. For mandarins, ignore the pressure to find perfectly orange skin; a small green blush is a natural, beautiful sign of ripeness that the commercial industry often masks with hormone treatments.
Your strategy should shift based on whether you intend to eat the skin or the flesh. For kumquats, where the skin is the primary delicacy, you must wait until the fruit is fully orange with no green spots to ensure maximum sweetness. Conversely, for oranges where the skin is discarded, focus on the feel of the fruit rather than its color. Once harvested, store your citrus in the refrigerator crisper drawer, avoiding plastic bags, and aim to consume them quickly to enjoy the full benefit of your harvest.
