Frequently Asked Questions

How Do You Prepare Leeks?

Leeks are a delicious vegetable that is underrated in the culinary world, mostly because people do not prepare them properly.

The ideal leek is no more than an inch and a half in diameter – any larger and they are not tender and the middle becomes fibrous and woody.

You need to chop off the top and bottom of your leeks to clean them properly and then rinse well under cold water to get rid of any dirt. If the recipe calls for chopped or sliced leeks, do this first before washing them as the dirt will come out much easier.

The dark green parts of a leek are tougher than the white and light green parts so it is sometimes better to remove the dark green parts and use them for something else.

Using only the most tender parts of the vegetable is particularly important when you are cooking something light or delicate and the green outer leaves can easily be used in a stock or soup at a later date.

How Do You Prepare Spinach?

Most baby leaf spinach is sold ‘ready to eat’ which usually means that it has been trimmed and washed for you. If you can’t get hold of this spinach or want to clean it again yourself you do need to do so properly to prevent any damage to the leaves.

Before you wash your raw spinach, it is a good idea to remove the stems. These stems can be a little fibrous when cooked and tough when raw so, as the dark green leaves on a leek, take the stems to use in a soup or stock.

Next, run the spinach under cool water. Take care not to damage the leaves as they will look a little unattractive in your dish. You can either dry spinach in a salad spinner or by spreading it out over a towel and placing another over the top.

This process takes a little longer than using a spinner but is best for those who don’t have all the gadgets in the kitchen.

How Do You Prepare Mushrooms?

Cleaning mushrooms is very important as their skin attracts and holds onto dirt and soil – not something that you want to be eating! Despite this, many people avoid cleaning mushrooms as they can get soggy as the gills absorb water.

To clean your mushrooms properly you can wipe them with a damp cloth, gently dust with a mushroom brush, or you can do it the professional way. This involves tipping the mushrooms into a large bowl of cold water that has had a handful of flour mixed in.

All you need to do now is gently rub the mushrooms against each other in a motion that is similar to intense handwashing, then immediately move them to a towel to dry. 

You can of course avoid all of this by peeling the mushrooms before you use them. This will remove any dirt or soil and get rid of the skin that can get leathery.

What Mushrooms Should You Use For A Tart?

The type of mushroom you use in a tart will depend on your flavor preferences. That said, the vast majority of recipes will use the white button mushroom as these are the most widely available. They are also the mildest flavored mushroom. 

If you want a mushroom that tastes earthy and woodsy, try the shiitake and opt for dried shiitake if you want a really intense flavor. The maitake mushroom is earthy like the shiitake but also gives a gamy aroma and flavor which is perfect for adding umami to your dish.

If you want to inject some sweetness to help balance the flavors of your dish you should try the beech mushroom that combines sweetness and nuttiness. The King Trumpet, meanwhile, is as meaty as the shape of the trunk would suggest!

As there are so many varieties of mushrooms, it is a great ingredient to experiment with and to develop your own style of cooking. This makes them a fantastic beginner-cook vegetable, especially as they are technically impossible to overcook!
