Slippery jack

Slippery jack, also known as the orange birch bolete (Leccinum versipelle), is a type of edible mushroom. It grows in ectomycorrhizal association with birch trees, primarily in northern temperate regions. The mushroom is known for its slimy cap when wet, hence its common name.

Slippery jacks are used as a food ingredient for their earthy, mushroom flavour and meaty texture. They are often incorporated into dishes like risottos, pasta fillings (such as tortellini and pierogi), and soups. Their distinct flavour profile makes them a popular choice for adding depth to savoury recipes.

Slippery jacks are a whole food, not a food additive, and are not listed on the Register of Food Additive Authorisations. As a mushroom, they are a source of nutrients like B vitamins and minerals, and contain dietary fibre. Like other mushrooms, they can be a source of umami flavour.
