The Grading Of Porcini Mushrooms: A Guide

Porcini mushrooms are graded according to quality level and slice size. The highest grade is usually AA, which is characterised by its size, lack of wormholes, ivory interior, milk chocolate exterior, and fragrant aroma. Other grades include AB, which is used for pastas and sauces, and 'Extra Grade', which is reserved for flash-frozen porcini mushrooms. Porcini mushrooms are also graded according to tolerances, which allow for variations in grading and handling, such as open veils, disease, spots, decay, and off-size.

Grading criteria: wormholes, size, colour, broth aroma, and flavour

Porcini mushrooms are graded according to quality level and slice size. The highest grade, Grade AA, is reserved for porcini mushrooms with no wormholes, an ivory interior, and a milk chocolate exterior. These mushrooms also produce a dark, fragrant broth with a pervasive aroma. In terms of size, Grade AA porcinis are considered to be the perfect size, although specific measurements are not always provided.

Wormholes are a significant factor in grading porcini mushrooms. While Grade AA mushrooms should have no wormholes, lower grades may have a small number of wormholes present. For example, one customer review mentions "very few worm holes, crumbs, or litter" in their description of Grade AA porcini mushrooms, while another expresses disappointment at finding worms in their Grade AA purchase.

The colour of porcini mushrooms can also play a role in grading. The coveted Grade AA designation is given to mushrooms with an ivory interior and a milk chocolate exterior. However, other colour variations exist, such as green spore tubes, which may be graded differently.

The aroma and flavour of porcini mushrooms are crucial factors in the grading process. Grade AA porcinis are known for their exceptional aroma, permeating the room with a fragrant broth. Their flavour is also highly regarded, with a rich, earthy taste that enhances soups, stews, and pasta sauces. Lower grades may still possess a good aroma and flavour but may not be as potent or pervasive as the highest grade.

Finally, the size of the porcini mushroom slices is considered during grading. Customers appreciate larger slices as they are more attractive and versatile in cooking. Smaller slices may be more suitable for specific applications, such as soups or stews, where the mushrooms need not be the highlight of the dish.

Grades: Extra, Super Premium AA, AB, and AAA

Porcini mushrooms are graded according to their quality level and slice size. The highest grade is Extra, followed by Super Premium AA, then AB, and finally AAA.

Extra Grade

The highest grade of porcini mushrooms is the Extra Grade. These mushrooms are carefully hand-brushed to preserve their flavour and texture and are sorted for freezing, drying, or processing within 24 hours of being brought in from the field. Extra Grade porcini mushrooms are clean, full slices with lots of flavour.

Super Premium AA

The Super Premium AA grade of porcini mushrooms is characterised by its perfect size, absence of wormholes, ivory interior, and milk chocolate exterior. They produce a dark, fragrant broth with a room-filling aroma. They are best prepared by sautéing or grilling with garlic and ginger and are well-suited for steaks, salads, soups, and stews.

Grade AB

Grade AB porcini mushrooms are pre-sliced, easy to rehydrate, and add a meaty texture and nutty flavour to meals. They are commonly used in pastas and sauces.

Grade AAA

Although there is limited information on Grade AAA porcini mushrooms, a customer review on Amazon mentions that the smaller pieces of porcini mushrooms are considered AAA, while the larger ones with green spore tubes are graded lower.

Uses: soups, quiche, stews, pasta, risotto, sauces, and more

Porcini mushrooms are a versatile ingredient, used in a wide variety of dishes. They are prized for their rich, nutty, earthy taste and meaty texture.

Fresh porcini mushrooms can be sautéed, braised, fried, grilled, or stewed. They are often served as a side dish or added to risottos and pasta.

Dried porcini are used to add a rich, deep mushroom flavour to broths, soups, stews, sauces, and risottos. They are also used as a meat substitute in vegetarian and vegan dishes. The liquid from rehydrating dried porcini can be used as broth in a soup or risotto.

Porcini mushrooms are commonly used in Italian and French cuisine. They are used in recipes for pasta, rice dishes, soups, sauces, and savoury specialties like risotto. Porcini mushrooms are also used in omelettes and pair well with poached eggs. The mushrooms can stand alone in a simple pasta dish or be combined with other ingredients like chicken or spinach.

Porcini mushroom powder is a versatile and easy-to-use way to add a gourmet touch to soups, sauces, risottos, and more. It has a more concentrated and intense flavour than fresh porcini mushrooms.

Preparation: dried, flash-frozen, powdered, and canned

Dried Porcini Mushrooms

Dried porcini mushrooms are a great way to add flavour to a dish. They are often sliced or powdered and can be soaked in water to reconstitute them. When buying dried porcini mushrooms, look for those that have been cleaned by hand and are free of soil and pin holes. The best-dried porcini mushrooms will have no worm holes and will produce a dark, fragrant broth.

Flash-Frozen Porcini Mushrooms

Flash-frozen porcini mushrooms are a convenient option that maintains the flavour and aroma of freshly picked mushrooms. They can be added directly to dishes when cooking and do not need to be thawed first. Flash-frozen porcini mushrooms are a favourite among high-end chefs as they are expertly sorted, graded, and hand-washed.

Porcini Mushroom Powder

Porcini mushroom powder is a great way to add umami flavour to vegan and vegetarian dishes. It has a concentrated and intense flavour compared to fresh porcini mushrooms. The powder is made from dried porcini mushrooms that have been rigorously selected and graded to ensure the best taste.

Canned Porcini Mushrooms

While I could not find specific information on canned porcini mushrooms, it is likely that they would be prepared similarly to other canned mushrooms. Canned mushrooms are typically already cooked and can be added directly to dishes or used as a topping. They may be packed in water or oil to preserve freshness and flavour.

Origin: Italy, the Himalayas, and Washington State

Porcini mushrooms are graded according to quality level and slice size. The highest grade is AA, which has no wormholes and is characterised by an ivory interior and milk chocolate exterior. AA porcini mushrooms are typically more expensive, with Italian AA porcini being worth around $75 per pound.

In Italy, porcini mushrooms are a key ingredient in risotto con funghi (rice with mushrooms). They are also commonly used in soups, quiche, stews, pasta sauces, pot roast, side dishes, and stuffings.

In the Himalayas, there is limited information on the grading of porcini mushrooms. However, porcini mushrooms are known to grow in this region, and they are likely graded based on similar quality and size standards as in other parts of the world.

In Washington State, porcini mushrooms are available during both spring and fall seasons. Mushroom hunters seek out "mushrumps," or rounded bumps in the duff that indicate the presence of a mushroom forming underground. The spring variety of porcini mushrooms in Washington State is particularly sought-after, as they are known to have a richer flavour than their fall counterparts.
