Mint Pesto
1largehandful of mint leaves (approx 40g)
30galmonds
30gfinely grated parmesan
2clovesgrated garlic
1lemon (zest)
hot water
salt and pepper
Instructions
Gently sweat the onions, leek, spices and thyme in a little olive oil over low heat.
While the onions are cooking, peel the celeriac and add to the onions as you chop. Cut the celeriac into approximately 3 cm cubes. Squeeze over a little lemon juice.
When the onions are translucent and the celeriac has started to soften - add all the stock and the parmesan rind.
Peel and core the pears and add them immediately to the soup as you peel - to stop them from browning!
Simmer gently for 30-40 minutes or until the celeriac is soft and blendable.
Remove the parmesan rind and thyme sprig. Blend the soup and check for seasoning adding salt, black pepper and a tablespoon of cider vinegar. If it is too thick for your taste - add a little milk, water or stock and reheat.
Mint Pesto
Blanch the mint leaves in hot water and then immediately into iced water. This stops them from browning.
Add the almonds to the mini-blender and whizz until fine. Add the remaining ingredients except for the water and blend. If you want it a little smoother but not oilier - add a little warm water to help you get the right consistency. Add salt and pepper to taste.
Serving
Serve hot, garnished with mint pesto and fresh bread.

Notes
It is important to blanch the mint leaves, or they tend to turn brown, and you lose the lovely bright green colour of the pesto—a great how-to post on blanching herbs here.If you want to prepare the celeriac in advance - it needs to be covered with water acidulated with either lemon or vinegar - to stop it from browning.The green peppercorns give the soup a slightly spicy kick but can be replaced with black peppercorns or a combination of white and black pepper.
