Step-by-Step Guide to Making Mary Berry White Sauce
Step 1 — Melt the butter
Warm the saucepan over medium heat and let the butter melt gently without browning.
Step 2 — Add the flour
Stir in the plain flour until it forms a smooth paste known as a roux. Cook for a minute to remove the raw flour taste.
Step 3 — Pour in the milk slowly
Add the milk in small amounts while whisking continuously. This prevents lumps and creates a silky consistency.
Step 4 — Simmer to thicken
Keep whisking as the sauce gently heats. Within a few minutes, it will thicken into a smooth white sauce.
Step 5 — Season the sauce
Add salt, pepper, and nutmeg if using, adjusting the flavour to your preference.
Step 6 — Use immediately or store
Serve hot or allow to cool before placing it in an airtight container.

What I Got Wrong (And How I Fixed It)
- Lumpy sauce – Whisking consistently and adding milk gradually solved this quickly.
- Sauce too thick – A splash of warm milk thinned it to the right texture.
- Flour taste still present – Cooking the roux a little longer removed it.
- Sauce forming a skin – Covering the surface with cling film prevented this.

FAQs
How do I stop white sauce from becoming lumpy?
Lumps form when milk is added too quickly, or the roux isn’t whisked well. Pour the milk in gradually while whisking continuously. Keeping the heat at medium also helps the mixture thicken evenly.
Why does my white sauce taste like raw flour?
The flour needs at least one minute of gentle cooking in the melted butter before adding any milk. This step removes the raw taste and creates a smooth, well-balanced flavour.
How do I fix white sauce that becomes too thick?
If the sauce thickens more than expected, whisk in a small amount of warm milk until it returns to your desired consistency. Add it slowly to avoid thinning it too much.
Can I make white sauce without dairy milk?
Yes, unsweetened oat milk, soy milk, or almond milk work well. Make sure to use plant-based butter or oil to keep the sauce fully dairy-free.
