Shima rakkyo is in season roughlyfrom spring to early summer, March to June. During this period new-crop shima rakkyo circulates, and the balance of pungency, aroma, and texture reaches its best state. At Okinawa's markets and farm stands, it is often sold as "new shima rakkyo" during the season.

• March–April: early new crop. Juicy, with a gentle bite
• April–May: peak season. Pungency and aroma grow stronger
• May–June: mature ones circulate. Ideal for salt-pickling
• From summer on: circulated year-round as preserved and processed goods (salt-pickled, dried)

The nutritional components and health effects of shima rakkyo

Shima rakkyo's distinctive pungency and aroma contain components common to negi, garlic, and the rakkyo family, making it an ingredient to work into daily meals. We organize the representative components and their expected roles below.

• Allicin (allyl sulfide): an aroma and pungency component common to garlic and the negi family
• Dietary fiber (fructan): a water-soluble dietary fiber, as an ingredient for meals mindful of gut environment
• Vitamin C: a water-soluble vitamin worth taking in mindfully in daily meals
• Potassium: a mineral component found in vegetables and fruits
• Polyphenols: a plant-derived functional component

The role of each component and appropriate intake guidelines can be checked in the Ministry of Health, Labour and Welfare's e-Healthnet,, and the Ministry of Education, Culture, Sports, Science and Technology's Food Composition Database . This does not guarantee a medical treatment effect; the basic idea is to work it in within the overall balance of your diet.

The basics of prepping and cooking shima rakkyo

To eat shima rakkyo deliciously, prep is important. Once you master the basic steps of peeling, root-trimming, and washing, you can apply them to any cooking—salt-pickling, tempura, or champuru.

• 1. Wash under running water: remove the soil
• 2. Trim the roots: cut off the root base flat with a knife
• 3. Cut the leaves: use the green leaves as a condiment; if using only the white part for cooking, cut them apart
• 4. Peel the thin skin: rub with the back of the knife to remove the thin skin (peel one layer and it's shiny)
• 5. Soak in salt water or vinegar water: if you want to soften the pungency, for about 5–10 minutes

The leaf part can be chopped and used as a condiment, so don't throw it away—make use of it. Whether to leave the thin skin on can be adjusted by dish.

Recommended ways to eat shima rakkyo | Salt-pickling, tempura, champuru

We introduce three standard ways to eat shima rakkyo. These are cooking methods beloved in Okinawa's izakaya and home cooking, requiring no difficult technique.

Salt-pickled shima rakkyo (standard)

• Sprinkle salt over the prepped shima rakkyo and rub lightly
• Put in an airtight container or zipper bag and let rest in the refrigerator for half a day to a day
• Before eating, rinse and top with a little katsuobushi and soy sauce

Order "salt-pickled shima rakkyo" at an Okinawa izakaya and this simple dish comes out. The sharp bite and crisp texture go well with awamori and beer.

Shima rakkyo tempura

• Dust the prepped shima rakkyo with cake flour and coat with batter
• Fry crisp in 180°C oil (briefly)
• Eat it clean with salt, tentsuyu, or kabosu

Heating makes the pungency mild and changes the texture to a fluffy one. It is popular as a snack with beer and awamori too.

Shima rakkyo champuru

• Slice the shima rakkyo diagonally and stir-fry with pork, shima tofu, nira, canned pork, etc.
• Season with salt, soy sauce, and katsuobushi

Adding shima rakkyo to the Okinawan home dish "champuru (stir-fry)" makes its aroma and pungency an accent that whets the appetite.
