Who needs which format?

The menu determines whether a block, a spreadable tub or both belong on the shopping list.

Hosts cooking with butter

If recipes call for regular butter in sauces, baking or finished dishes, work out how much they require before choosing a pack. ASDA Groceries lists 500g Asda and Kerrygold salted blocks made from butter and salt.

Hosts serving bread or rolls

A spreadable tub is worth considering when guests will serve themselves straight from the fridge. Tesco Groceries lists 500g Lurpak and 750g Anchor options; their blended formulations differ from a plain butter block.

Hosts catering for dairy-free guests

The Asda, Kerrygold, Lurpak and Sainsbury's products discussed here contain milk. Check the label on the pack you buy and arrange a separately labelled dairy-free option if a guest needs one.

What should you check before buying?

Start with how the butter will be used, then match the pack size to the menu and check its ingredients and storage directions.

Priority What to check Your needs
Cooking format Check whether the recipe specifies regular butter. ASDA Groceries lists its 500g salted block as butter and salt; Anchor recommends its regular block rather than its spreadable blend for cooking. My recipes call for butter, so I need to keep a butter-and-oil spread separate unless a recipe allows that substitution.
Table service Check the product description and ingredients if guests will spread it straight from the fridge. Tesco Groceries describes Lurpak Spreadable 500g as a blend containing milk fat and rapeseed oil. Bread or rolls will be on the table, and I want guests to be able to serve themselves without waiting for a block to soften.
Pack quantity Add up the amounts specified in the recipes and allow separately for table service. The documented options include 500g blocks and spreadable packs, plus an Anchor 750g spreadable pack listed by Tesco Groceries. I need enough for both the dishes and the bread basket, without assuming that one 500g pack will cover every menu.
Ingredients and milk Read the physical pack's ingredient and allergen information. The butter blocks and spreadable blends discussed here contain milk; a spreadable blend may also contain vegetable oil. A guest needs a dairy-free option, so I must choose a separately labelled product for them rather than rely on the word “spreadable”.
Dates and storage Check the date and refrigeration instructions on the pack. Follow any product-specific freezing directions rather than assuming every format can be stored in the same way. Some of the pack may remain after the dinner party, so I want storage instructions that fit how I plan to use the rest.

Common buying mistakes

  • Treating a spreadable blend as an ordinary butter block

    Tesco Groceries describes Lurpak Spreadable as containing milk fat and rapeseed oil, while ASDA Groceries lists its salted block as butter and salt. That ingredient difference matters when a recipe calls specifically for butter.

    Read the ingredients before using a spreadable tub in a recipe. Anchor recommends its regular block butter for cooking; keep the tub for bread service unless your recipe permits the blend.

  • Assuming every guest can have the same butter

    The Asda and Kerrygold blocks and the Lurpak and Sainsbury's spreads discussed here contain milk. A dairy-free guest therefore needs a different product.

    Ask about dietary requirements before shopping and check the physical labels of both the butter and any separately chosen alternative.

  • Choosing a large pack without checking its date

    A pack left over after the event still needs to be stored according to its label. GOV.UK distinguishes best-before dates, which concern quality, from use-by dates, which concern safety.

    Check the date on the pack you buy, follow its refrigeration directions and freeze it only where its instructions permit.

Brand and retailer references

These examples show why the format and ingredients on a particular pack matter more than the brand name alone.

Lurpak

The Lurpak Spreadable Slightly Salted 500g pack is a blended table-spread option listed by Tesco Groceries.

  • Tesco Groceries describes the pack as a 75% blended spread containing 52% milk fat and 23% rapeseed oil.
  • It is not the same formulation as a plain block of butter and contains milk.

Anchor

Anchor has a 750g Original Spreadable option for table service.

  • Tesco Groceries lists the 750g pack, and Anchor describes its spreadable product as a butter-and-rapeseed-oil blend.
  • Anchor recommends its regular Original Block Butter for cooking rather than assuming the spreadable blend suits that use.

Kerrygold

Kerrygold Salted Pure Irish Butter 500g is a block option listed by ASDA Groceries.

  • Its listed ingredients are butter and salt, with a minimum 80% fat content.
  • It contains milk; a chilled block also needs consideration if guests will spread it themselves.

Tesco

Tesco Groceries provides product listings for branded spreadable packs in different sizes.

  • Its listings include Lurpak Spreadable Slightly Salted 500g and Anchor Original Spreadable 750g.
  • Check each pack's ingredients and weight rather than treating all products in the spreadable category as identical.

Sainsbury's

Sainsbury's Buttersoft Spreadable 500g is an own-label blended spread.

  • Sainsbury's describes it as a 78% blended spread containing 52% milk fat and 26% vegetable oil.
  • It contains milk and is not a plain butter block.

Asda

ASDA Groceries lists both a 500g salted butter block and a 500g slightly salted spreadable product.

  • The block is listed as butter and salt with a minimum 80% milk-fat content.
  • The spreadable product has a different formulation: its listed ingredients include butter, rapeseed oil and water. Both products contain milk.

Joybuy option for dinner-party cooking

This 500g ghee is a butter-derived option for a menu that specifically calls for ghee. It is not a conventional butter block or a spreadable tub, so check the recipe before treating it as a substitute for either.

Laila Pure Butter Ghee 500g pack

Laila Pure Butter Ghee 500g

For dinner-party cooking that calls for ghee, this is a 500g pack. It contains milk; check the recipe before substituting it for regular butter, and do not assume it is suitable for spreading on bread.

Dinner-party butter questions

Should I buy a block or a spreadable tub for a dinner party?

Choose a block when recipes call for regular butter, and consider a spreadable tub when guests will serve themselves bread straight from the fridge. The Asda and Kerrygold blocks listed by ASDA Groceries contain butter and salt; the spreadable examples include blended ingredients, and Anchor recommends its regular block for cooking.

Will one 500g pack be enough?

That depends on the quantities in your recipes, the number of guests and whether butter is needed at the table as well as in cooking. Add up those uses before buying; if both formats matter, a separate block and spreadable tub lets you keep the cooking quantity apart from the bread service.

Are these butter and spreadable packs dairy-free?

No. The Asda, Kerrygold, Lurpak and Sainsbury's examples discussed here contain milk. Check the physical label of any pack you buy and choose a separately labelled dairy-free product for a guest who needs one.

What date and storage details should I check?

Read the date and storage instructions on the actual pack, especially if you expect leftovers. GOV.UK explains that best-before dates concern quality whereas use-by dates concern safety; follow the product's refrigeration and any stated freezing directions.
