Costack blends are boldly flavoured and ready to transform any meal. No mixing, no guesswork, just rich taste in every shake. Our range covers everything from everyday garlic and thyme to blends like Smoky Peanut BBQ Rub and Mild Curry Powder that you will not find on a standard supermarket shelf.
All Costack spices carry a clearly printed best-before date on the packaging. Stored in a cool, dry place away from direct sunlight, our blends typically last 18 to 24 months from production.
Most of our blends are flavour-forward, not fire-forward. All Purpose, Complete Seasoning, and Chicken and Turkey are warmly spiced but family-friendly. Cameroon Pepper and Suya Spice carry real heat. Every product page lists the heat level so there are no surprises.
We offer 19 bold spice blends, including Smoky Tomato Rice Seasoning, Smoky Peanut BBQ Rub, Hot Smoky Chilli Powder, Mild Curry Powder, Lemon Pepper, Adobo Seasoning, Aromatic Hot Broth Spice, Complete Seasoning and All Purpose Seasoning. Whether you are cooking chicken, fish, rice, soup or vegetables, there is a Costack blend made for it.
Our single spices and herbs, like Garlic Granules, Ground Ginger and Dried Thyme, are 100% pure with nothing added. Some savoury blends, including Complete Seasoning, Chicken and Turkey, Meat, Fish and Seafood, Smoky Tomato (Jollof) Rice, Vegetable Seasoning and Seafood Stock Powder, contain flavour enhancers such as E621 (MSG) and E635 for savoury depth. Every ingredient is listed on the product label and product page in compliance with UK food labelling law.
The majority of our spice blends are plant-based and suitable for vegetarians and vegans. Always check the individual product label for the full ingredient list. Some blends like our Crayfish Stock Powder contain shellfish-derived ingredients. Allergen information is clearly displayed on every product.

A note from Fred

My customers are so dear to me.

I started Costack in 2014, for people who actually care what is in the bottle and sachet. One blend at a time. No shortcuts.

Twelve years on, I still taste everything we sell. I still read every message. When you reorder, I notice.

Thank you for cooking with us. Welcome if you are new here.
