What is Celeriac?
Celeriac is an edible root vegetable that is the bulbous part of a species of the celery plant. It can be eaten raw or cooked.
Celeriac is available year-round, and stores well, but it's best when bought between September and April.
Also called Celery Root, it is not from the same species as the regular stem celery you buy, but is cultivated for the large edible roots.

- Fresh Garlic - Infuses this side dish with fresh garlic flavor.
- Milk - Gives the dish its classic creamy taste and texture. You can swap to heavy cream (double cream) to make it even more creamy.

Tips
You can omit the potatoes, it just won't be as creamy.
You can use any potato for this recipe, but the best potatoes to use for mash are golden potatoes. They are naturally more buttery and soft on the inside which makes for a smoother mashed potato.
The outside peel of celery root is very rough and tough. You may need to use a sharp paring knife to remove the peel instead of a vegetable peeler.
The level of garlic flavor is in your control. You can choose to mash the cooked garlic into the potato celeriac mixture or remove the whole cloves before mashing.
If you want a really smooth mash, cook the celeriac and potatoes separately. Puree the celeriac in a blender, and mash the potatoes separately, then stir them together.

FAQs
Celery is a long green stalk vegetable that grows on top of the soil. Celeriac is the bulb that grows underneath the ground from which the celery stems from.

Not technically even though it is a root. Celeriac is only 5-6% starch which is much lower than potatoes or pumpkin squash.
Celeriac, the nobbly round root vegetable, has a mild celery flavour with a slightly nutty taste too.
Celeriac is a versatile root vegetable. It can be mashed, pureed, added to soups and stews, roasted, or eaten raw. It's popular in France served raw in a creamy remoulade, similar to coleslaw.
