Making Vegetable Stock from Scratch
A robust vegetable stock comes from simmering aromatic scraps and fresh vegetables in water for exactly one hour; any longer, and the liquid turns bitter and grey. You need a high ratio of onions, carrots, and celery, balanced with neutral herbs like parsley or bay leaves, to create a base that holds its own in soups and sauces.
Watch your scraps and timing.
Avoid using cruciferous vegetables like broccoli or kale, as they ruin the batch with a sulfurous tang. Keep your simmer gentle; a rolling boil emulsifies the starch and clouds the stock.

Developing Base Notes
Sautéing your aromatics in oil for ten minutes before adding water caramelizes the sugars, providing depth that plain boiled vegetables cannot reach.
The method.
Sweat the vegetables
Heat oil in the stockpot over medium heat. Add onions, carrots, and celery. Stir frequently for 10 minutes until the onions lose their raw edge and take on a pale gold hue.
Simmer
Add garlic, herbs, and peppercorns. Pour in the cold water. Bring to a gentle bubble, then turn the heat to the lowest setting. Simmer uncovered for 50 minutes.
Strain
Place a fine-mesh strainer over a clean bowl. Pour the stock through, pressing lightly on the solids to extract liquid, then discard the solids immediately.
Cool
Let the stock reach room temperature before moving it to the refrigerator. Skim any floating bits once fully chilled.
Other turns to take.
Roasted Stock
Toss the carrots and onions in oil and roast at 400°F until dark brown before adding to the pot for a deeper, earthier profile.
Fungal Infusion
Add two or three dried shiitake mushrooms to the pot for a heavy dose of umami.
When it doesn't go to plan.
Keep a dedicated freezer bag for clean vegetable trimmings—onion ends, carrot peels, celery leaves—to toss into your next batch.
Do not add salt while simmering; keep it unseasoned so you can control the salt levels of your final dish later.
Use cold water to start, as it draws out the vegetable essences more gradually and cleanly than hot water.
The ones that keep coming up.
Why is my stock cloudy?
You likely boiled the vegetables too vigorously. A steady, barely-there simmer keeps the liquid clear.
Can I freeze this?
Yes. It keeps for up to three months in airtight containers. Leave an inch of space at the top, as the liquid will expand.
