Fresh oyster mushrooms

Fresh mushrooms – delicious local food!

Our oyster mushrooms are available all year round! In the Helsinki metropolitan area, you can enjoy Helsieni’s fresh oyster mushroom grown in Espoo. The mushrooms are best when freshly harvested, but they last in the refrigerator for at least 10 days. Our selection also includes other fresh seasonal mushrooms.

Helsieni’s mushrooms bring to mind many things: always fresh, they store well and most importantly: delicious. I admire the passion of the growers, which is reflected in the quality.

Dried yellowfoot, shiitake and oyster mushrooms

Dried mushrooms

We dry the mushrooms we grow when the harvest has been particularly abundant. Drying is one of the best ways to preserve mushrooms and it even increases their umami flavour. Dried mushrooms save your busy day and do not take up much space – 100 g of dried mushrooms is equivalent to almost 1 kg of fresh mushrooms! See the selection in our online store.

Sienijerky slices

Mushroom jerky

Mushroom jerky is a salty snack made of oyster mushrooms that tastes great alongside a cold drink. Chew a few pieces for an easy snack or take it out for a picnic – it is super light to carry!

The mushroom jerky is hand-made at the Helsieni Farm in Espoo.
