Peel the pearl onions and shallots expect to cry just a little, I cried a lot!
Put the pearl onions in a separate bowl for later.
Take 300g mushrooms and cut into slices.
Cut the large carrots into slices, not too thick and not too thin. These will become buttery soft and that's a part of the plan.
Slice the shallots and crush the garlic with the back of a large knife and slice them as well.
This is what it should look like when all is prepped.
Blanch the pearl onions by putting them into boiling water for 3 minutes and then put them into ice cold water for a few minutes to stop the cooking.
This is what they will look like when they are done.
Brown the pearl onions in a little salted butter and put them in a small bowl for later.
The mushrooms should be browned in salted butter and the most important thing is that you don't toss them into the skillet all at once. Mushrooms should be sautéed with plenty of butter and plenty of space in-between them, as this will make them develop a pleasant nutty and buttery flavor in the dish, as they are cooked correctly and evenly. Many people don't do that and that is probably why mushrooms tend to get a bad rep in stews (especially with children). Because undercooked mushrooms develop an extremely unpleasant flavor (a swampy one), as they have not been drained of their excess liquids, because they haven't been cooked properly. I browned mine using the skillet twice and turned them with tweezers. When they have a nice golden color, set them aside in a bowl for later, if they are browned correctly, you will not find any excess liquid at the bottom of that bowl when you are adding them to your dish, so let that be your browning test.
Lightly brown the carrots with the shallots in plenty of butter. You might need to use more butter than what I added to this recipe. Do not be afraid of butter!
Add the spices and set aside the vegetables in a bowl for later.
