Omasari is a japanese jambo peanuts, very tasty when boiled. If you want to eat freshly-boiled peanuts, here’s how to get them, how to boil them, and how to preserve them!


What is the giant peanut “Omasari”?

The Omasari is a new variety created in 2007 after 14 years of breeding by Chiba Prefecture, Japan. It is about twice the size of a regular peanut. Its sweetness and softness make it an excellent choice for boiling in salted water, and its large size is very satisfying and tasty. With its unprecedentedly tender texture and striking appearance, it has been rapidly gaining popularity over the past few years. The harvest period is from the beginning of September to the end of October, and because they cannot be preserved, fresh Oomasari peanuts are basically only available during this period. (Most of the peanuts available outside of this period have already been boiled and preserved, so they are available year-round if they are in stock.)

Omasari are so big they stick out of your hand!

You can see that they are very large compared to regular peanuts. (The left side of the photo is Satonoka peanuts and the right side is Omasari.)

How to boil fresh peanuts

If there are leaves attached to the peanut, peel off the shell and remove the mud. After boiling, they are delicious eaten warm or chilled in the refrigerator.

Recipe A (pressure cooker)

  • 500 g raw peanuts (Omasari)
  • Water
  • 15 g salt (2-4% of peanuts)
  1. Put raw peanuts in a pressure cooker and fill with salted water up to the level of the peanuts.
  2. Cover tightly and bring to a boil over high heat.
  3. After 5 minutes, turn off the heat and let the peanuts steam for about 10 minutes.
  4. Open the lid, check the boiling and it is done! (If the pot is not cool enough, put the pot in a bowl of water to cool.)

*If you like it firm, try shortening the boiling time to about 3 minutes.

Recipe B (regular pot)

  • 500 g fresh peanuts from Omasari
  • 1.5L water
  • About 25 g salt
  1. Put raw peanuts, water, and salt in a pot.
  2. Cover with a drop-lid and boil over medium heat for 30-40 minutes. Stir a few times before boiling.
  3. If the water level becomes lower than the peanuts during boiling, add water to bring the water level back to the original level.
  4. After boiling for 30 minutes, check the boiling time.
  5. Boil for 30 minutes, the core of the peanuts will remain a little soft. If you like them softer, boil them for another 10 to 20 minutes and they are done!

The coloring of the astringent peel will ooze out in this method, and the color of the pods will turn a little darker after boiling (the taste is not affected). (This does not affect the taste.) If you are concerned about this, you can avoid this by refreshing the water during the boiling process.

How to store boiled peanuts

Boiled peanuts do not last long, so we recommend storing them in the refrigerator and eating them within 2 to 3 days. If you can’t finish eating them, you can store them in the freezer for a longer period of time.

How to obtain fresh Omasari peanuts?

They are available for a limited time from early September to the end of October. They are sold at peanut shops, grocery stores, and supermarkets near peanut producing areas. Because fresh Omasari peanuts do not preserve well, they are rarely sold in stores in areas far from peanut-producing areas. In the case of mail order, they are basically delivered by refrigerated delivery.

Points to keep in mind when ordering peanuts by mail order

When you are looking for fresh boiled peanuts, there are three main types of products. Make sure that the product you are looking at is a “raw peanut”.

  • Raw peanuts from Omasari are ordered by refrigerated delivery and must be boiled immediately upon arrival. They can only be ordered from early September to the end of October. We recommend you to order freshly dug Omasari when you want to eat freshly dug Omasari with the amount of salt and boiling time adjusted by yourself.
  • Retort-packed boiled peanuts are available for order with regular delivery (at room temperature). You can order them all year round as long as they are in stock. They can be stored at room temperature, so they are recommended as souvenirs.
  • Boiled peanuts (frozen) In the case of the “Omasari’s Boiled Peanuts (frozen),” they are ordered by frozen delivery and stored in the freezer after arrival. You can defrost them in the microwave and eat them whenever you like. They are more reasonably priced than retort-packed peanuts, and are recommended when you want to eat them easily at any time of the year.

How to Store Fresh Omasari Raw Peanuts

Since Omasari raw peanuts cannot be stored, it is important to boil them as soon as you get them (preferably within 2 days). If you cannot boil them immediately, store them in the refrigerator and boil them as soon as possible. After boiling peanuts, they can be frozen for longer storage.

Notes on Omasari

  1. Fresh Omasari peanuts are a variety whose shells tend to turn black. If the peanuts are kept refrigerated all the time after harvesting for up to 5 days or less, the black shells are often fine inside, but if the shells turn black, please check the contents carefully.
  2. If you want to boil fresh peanuts that have been dried to dryness for preservation, soak them in water for a day and boil them longer, although this rarely happens.
  3. If you freeze freshly dug peanuts with a lot of water in them, they will lose their texture when thawed. In this case, you can minimize the deterioration of texture by boiling them in boiling water for a longer period of time or boiling them in a pressure cooker while frozen, instead of thawing them naturally.
