Description

Fireless cooker made of a woollen blanket for steaming food. The principle of the fireless cooker or Norwegian pot is to place a stewpot in an insulating receptacle after boiling for slow cooking without using a heat source. This specific space-saving model is perfectly suited to nomadic life, especially in a van, but not only, and can be adapted to various sizes of stewpot or saucepan.

Introduction

The fireless cooker is a steaming device that has been around for thousands of years. The principle is to place a pot in an insulated container after boiling for slow cooking without a heat source. In addition to saving energy, the other advantage is that the nutrients are preserved. The dishes are tasty because they are cooked slowly; we've tested and approved it extensively, particularly with lentil and soups.

Matériaux

• A blanket for a double bed (preferably wool)

• Fabric

• Sewing thread

• 2 Velcro strips, approx. 30 cm long

Outils

• A pair of scissors

• Needles

• Pins

• A sewing machine optionally

Étape 1 - Preparing insulation

• Fold the blanket into thirds and check that this is enough to enclose your stewpot.
• Cut the blanket into three squares of equal size
• With the rest, cut two squares the width of the stewpot
• Sew these two small pieces in top of each other at the centre of one of the larger squares to make a double base for the stewpot
• Overlay the three large squares on top of each other
• Sew them together by hand around the edges

Étape 2 - Making the cover

• Cut the fabric to cover both sides of the blanket squares
• Cut two Velcro strips about 30 cm long
• Position the Velcro strips on the fabric, making sure that the two opposite sides overlap when you close the Norwegian pot on the stewpot.
• Secure the Velcro strips to the fabric with pins
• Sew them to the fabric
• Fold the fabric in half, overlapping the edges
• Sew two edges of the fabric together to make the cover
• Slide the blankets squares into the cover
• Stitch in the centre to keep the blankets in place inside the cover
• Sew the last edge of the cover. You can also sew on a zip to make the cover easier to wash.
• You can now use your Norwegian pot!

Étape 3 - Using the fireless cooker

• Start cooking on the heat using your most isolated pot
• Place the lid on the pot and bring to the boil.
• Further cook for a few minutes (depending on the recipe chosen, the pre-cooking time will vary).
• Place your Norwegian pot wide open on a flat surface
• Stop cooking and place the boiling stewpot in the centre of the Norwegian pot
• Close the edges with the Velcro strips, taking care not to leave any gaps between the pot and the fabric.
• Allow to stew inside the Norwegian pot for the minimum time required according to the recipe, usually double the normal cooking time.
• Open the pot and check that it is cooked through and still hot.
• All you have to do now is enjoy your tasty recipe.

Étape 4 - Tips

• A wool blanket will limit the number of layers you need to use for insulation, but you can use other insulating materials.
• Velcro straps allow you to use different sizes of stewpot or saucepan. Make sure you make your Norwegian pot with the largest pot you're going to use.
• We recommend that you recycle materials. You can find woollen blankets and cotton fabrics at recycling centres.
• When cooking, it's best to choose a cast-iron or terracotta casserole, as the heat loses more slowly, but the most important thing is that the lid fits the pan properly so that it doesn't leak.
• Tighten the Velcro straps as much as possible to prevent heat loss.
• Make sure that there is enough water in the pot to simmer for several hours.
• If you have left your dish to simmer for more than 2 hours, there is a risk that the temperature will have fallen below 60 degrees and that bacteria will have developed. It is therefore advisable to bring your dish to the boil before eating it.
• You can use your Norwegian pot as a quilt over your duvet for extra warmth around the feet especially when it is still warm after having cooked!
