FAQs
Can I use only one type of vegetable?
Yes, though using all three creates a richer, more complex flavour.
Is mashing by hand okay?
Absolutely—just ensure the veggies are fully tender, or the texture may be coarse.
Can I make it ahead?
Yes—reheat with milk or stock; it also freezes well.
Can I skip the garlic?
You can, but the garlic gives a depth of flavour that enhances the mash.
What kind of nutmeg should I use?
Freshly grated nutmeg delivers the best aroma and taste.
