Harvest Tips
Finger limes typically fruit in spring/early summer. Harvest when fruits are fully yellow and slightly soft to gentle pressure. Cut with pruners rather than pulling to avoid branch damage. Fruits will not continue ripening after harvest, so wait until fully colored. Check for maturity by tasting one—flesh should be juicy and flavorful. Store at room temperature for 1-2 weeks or refrigerate for up to 3 weeks.
Fun Facts
- 🌱 Finger limes are native to the rainforests of northeastern Australia and have been used by Aboriginal peoples for thousands of years before becoming trendy in modern cuisine.
- 🌱 The 'Yellow Surprise' cultivar is a relatively new hybrid that combines the compact growth habit of dwarf rootstocks with yellow fruit production, making it more accessible for home gardeners than wild varieties.
- 🌱 Each finger lime contains dozens of juice-filled vesicles that burst individually in your mouth, creating a unique sensory experience similar to caviar—hence the nickname 'caviar lime' in culinary circles.
