Tatsoi (Brassica rapa subsp. narinosa) is an Asian variety of Brassica rapa grown for greens. Also called tat choy, it is closely related to the more familiar bok choy. This plant has become popular in North American cuisine as well, and is now grown throughout the world.

The plant has dark green spoon-shaped leaves which form a thick rosette. It has a soft creamy texture and has a subtle yet distinctive flavour.

Tatsoi is used for pesto, salads, stir frys and garnishing soup. According to Food52, "Tatsoi is a very versatile green, equally suited to being served raw or lightly cooked. To make it easy, just use tatsoi anywhere you’d use spinach. Lightly steam or sauté it, wilt the leaves with a warm dressing, or add them to a soup at the end of cooking."

The leaves are similar to romaine, while the stalks taste a little like cucumber, with a mild bitterness. Leaves and inner stalk are tender; outer stalk is typically discarded. Typical cooking is to stir fry the leaves and the stalks. They also can be pickled.

• Tat soi is a leafy green vegetable from the Brassica family that are often referred to as cruciferous vegetables.

• Other names for tat soi are rosette bok choy, broadbeak mustard, spinach mustard, or spoon mustard.

• Large heads of tat soi can be found at farmers markets but it is most commonly available as one of the mixed greens in prepared salad mixes.

• Tat soi can be eaten raw in salad and can be used like most cooked greens such as baby spinach. It can be sautéed, steamed, stir-fried, or mixed into soups or stews.

• Tat soi is considered a “cut-and-come again” leafy vegetable, allowing for multiple harvests on a single plant.

• Tat soi is an amazing source of vitamin C and a good source of vitamins A and K, carotenoids, folate, calcium and potassium.

• Fresh tat soi leaves contain twice as much calcium as milk. Milk contains 113 milligrams of calcium per 100 grams and tat soi contains 210 milligrams.

• This leafy green grows from April to June and again from September to November in New Jersey.

As you enjoy fresh produce, follow these safe handling tips to help protect yourself and your family.

Fruits and vegetables are an important part of a healthy diet. Your local markets carry a wide variety of nutritious fresh fruits and vegetables. However, harmful bacteria that may be in the soil or water where produce grows can come in contact with fruits and vegetables and contaminate them. Fresh produce may also become contaminated after it is harvested, such as during storage or preparation.

Eating contaminated produce can lead to foodborne illness, often called “food poisoning.” So as you enjoy fresh produce, follow these safe handling tips to help protect you and your family.

Buy Right

You can help keep produce safe by making wise buying decisions.

• Choose produce that is not bruised or damaged.
• When buying pre-cut, bagged or packaged produce — such as half of a watermelon or bagged salad greens — choose only those items that are refrigerated or surrounded by ice.
• Bag fresh fruits and vegetables separately from raw meat, poultry, and seafood when packing them to take home from the market

Store Properly

Proper storage of fresh produce can affect both quality and safety.

• Store perishable fresh fruits and vegetables (like strawberries, lettuce, herbs, and mushrooms) in a clean refrigerator at a temperature of 40° F or below. Use a refrigerator thermometer to check! If you’re not sure whether an item should be refrigerated to keep its quality, ask your grocer.
• Refrigerate all produce that is purchased pre-cut or packaged .

Separate for Safety

Keep fruits and vegetables that will be eaten raw separate from raw meat, poultry, and seafood — and from kitchen utensils used for those products.

• Wash cutting boards, dishes, utensils, and countertops with soap and hot water between preparing raw meat, poultry, and seafood and preparing produce that will not be cooked.
• If possible, use one cutting board for fresh produce and a separate one for raw meat, poultry, and seafood.
• If you use plastic or other non-porous cutting boards, run them through the dishwasher after use

Prepare Safely

When preparing any fresh produce, begin with clean hands. Wash your hands for at least 20 seconds with soap and warm water before and after preparation.

• Cut away any damaged or bruised areas on fresh fruits and vegetables before preparing and/or eating. Throw away any produce that looks rotten.
• Wash all produce thoroughly under running water before preparing and/or eating, including produce grown at home or bought from a grocery store or farmers’ market. Washing fruits and vegetables with soap, detergent, or commercial produce wash is not recommended. Produce is porous. Soap and household detergents can be absorbed by fruits and vegetables, despite thorough rinsing, and can make you sick. Also, the safety of the residues of commercial produce washes is not known and their effectiveness has not been tested.
• Even if you do not plan to eat the skin, it is still important to wash produce first so dirt and bacteria are not transferred from the surface when peeling or cutting produce.
• Scrub firm produce, such as melons and cucumbers, with a clean produce brush.
• After washing, dry produce with a clean cloth towel or paper towel to further reduce bacteria that may be present on the surface

What About Pre-Washed Produce?

Many pre-cut, bagged, or packaged produce items are pre-washed and ready-to-eat. If so, it will be stated on the packaging, and you can use the produce without further washing.

If you choose to wash produce marked as “pre-washed” or “ready-to-eat,” be sure that it does not come in contact with unclean surfaces or utensils. This will help to avoid cross contamination.

About Foodborne Illness

Know the Symptoms

Consuming dangerous foodborne bacteria will usually cause illness within 1 to 3 days of eating the contaminated food. However, sickness can also occur within 20 minutes or up to 6 weeks later. Although most people will recover from a foodborne illness within a short period of time, some can develop chronic, severe, or even life-threatening health problems.

Foodborne illness can sometimes be confused with other illnesses that have similar symptoms. The symptoms of foodborne illness can include:

• Vomiting, diarrhea, and abdominal pain
• Flu-like symptoms, such as fever, headache, and body ache

Take Action

If you think that you or a family member has a foodborne illness, contact your healthcare provider immediately.
