Home cooks making sauces, risotto or pasta
If cheese, stock or cured meat will contribute salt, an unsalted block leaves you room to season the finished dish. Check the salt declaration on the butter you buy.
Who is choosing butter for?
Hosts serving bread or finishing dishes
A salted block puts salt into the butter served at the table. If easy spreading straight from the fridge matters more, compare spreadable products separately rather than treating them as the same format.
Hosts catering for someone who avoids milk
The Food Standards Agency identifies milk as a common ingredient in butter. Ask guests about their requirements and check the exact pack before serving dairy butter.
What should you check?
Decide how the butter will be used, then compare salt, format and storage on the exact pack. Settle the quantity only once you know what each item on your shopping list measures.
| Priority | What to check | Your needs |
|---|---|---|
| Salt | Compare the salt figure per 100 g on the exact pack. Anchor lists 0.02 g per 100 g for its unsalted block and 1.7 g per 100 g for its Original salted block; these figures do not describe every butter. | If cheese, stock or cured meat is going into my sauce, I want to decide how much salt to add after tasting. |
| Format | Check whether the recipe specifies block butter and whether the product is a block, spreadable butter or ghee. Anchor lists different fat and salt figures for its Original Spreadable and salted block, so do not assume their formulations match. | I need a block for a recipe that calls for one, but easy spreading matters when butter is going straight onto bread. |
| Milk | Read the ingredient and allergen information on the pack. The Food Standards Agency identifies milk as a common ingredient in butter. | Before serving guests, I need to know whether anyone must avoid milk and arrange a suitable alternative if they do. |
| Storage | Follow the pack instructions. Anchor advises refrigerating its unsalted block until needed and always keeping its spreadable butter in the fridge. | When preparing ahead, I need to keep the butter stored as directed and bring out only what I plan to use. |
| Quantity | Compare the pack weight with the amount your recipe calls for. If your list says ‘4 pint’, establish what that volume refers to rather than treating it as a butter weight. | I want enough for cooking and serving, without guessing a butter quantity from a volume note that may refer to something else. |
What can catch you out?
-
Using salted butter without accounting for the rest of the dish
Salt from butter adds to what is already in cheese, stock, cured ingredients or pasta water. Anchor lists 1.7 g salt per 100 g for its salted block, compared with 0.02 g per 100 g for its unsalted block.
For a sauce or risotto with other salty ingredients, consider an unsalted block and season after tasting. If the recipe calls for salted butter, follow its instructions and check the pack.
-
Assuming spreadable butter is the same as a block
Anchor lists 77 g fat and 1.1 g salt per 100 g for its Original Spreadable, against 82 g fat and 1.7 g salt per 100 g for its salted block. Those products have different declared profiles.
Read the recipe and product label before swapping formats. If a recipe specifies block butter, choose that format unless the recipe allows a substitute.
-
Overlooking milk when serving guests
The Food Standards Agency identifies milk as a common ingredient in butter and a potential risk for people with a milk allergy or intolerance.
Ask about dietary requirements before cooking, check the exact pack and provide a suitable non-dairy option for anyone who must avoid milk.
-
Leaving butter out without checking its storage instructions
Anchor advises keeping its unsalted block refrigerated until needed and its spreadable butter refrigerated at all times.
Plan when to bring butter out for serving, refrigerate what remains and follow the pack’s storage and date instructions.

Questions about butter for an Italian night
Should I use unsalted butter for pasta sauce or risotto?
An unsalted block is a useful choice when cheese, stock, cured meat or pasta water will also contribute salt: you can taste the dish before adding more. Check the exact butter’s label, because its declared salt content depends on the product.
Can I use salted butter instead?
Yes, if its salt suits the dish or you want a salted butter flavour with bread. Account for that salt before adding more elsewhere; Anchor lists 1.7 g salt per 100 g for its Original salted block.
Can I serve butter to a guest who avoids milk?
Do not serve dairy butter to a guest who must avoid milk. The Food Standards Agency identifies milk as a common ingredient in butter; check the exact pack and arrange a suitable alternative.
How should I store butter before the meal?
Follow the instructions on the pack. Anchor advises refrigerating its unsalted block until needed and always keeping its spreadable butter refrigerated. Anchor also says its butter products can be frozen for approximately three months and defrosted slowly in a fridge at approximately 5°C.
