A custom spice blends manufacturer in India will make your recipe if you give it as exact percentages by weight, plus the grade of each ingredient. Curry powder and garam masala are the two most requested, and both are easy to get wrong because neither has one standard formula.
The work starts with a recipe sheet and a sample, not a purchase order. Expect two or three rounds of samples before you approve.
What a recipe sheet must contain
A recipe that says cumin, coriander, black pepper is not enough. The plant needs numbers it can weigh, and your quality team needs the same numbers to check against. Include these:
- Every ingredient with its percentage by weight, adding to 100.
- The form of each ingredient: whole, ground, roasted or raw, and the particle size of the final blend.
- The grade or origin of the main spices, for example the type of chilli or the colour level of turmeric.
- Limits you will test: moisture, colour, volatile oil or piperine where relevant, and microbiology for your market.
- Whether the blend may contain salt, anti-caking agent or any carrier, and which allergens must be declared.
Why garam masala and curry powder differ so much between brands
Garam masala is a family of blends. Some are built on cumin and coriander with a little cinnamon, cloves and cardamom, while others are warmer and sweeter. Our post on why garam masala varies between brands explains the spread. For a garam masala private label the practical point is that you must choose one profile and lock it, rather than ask for a typical one.
Curry powder has the same issue. A Madras-style blend is hotter and redder than a mild British-style one, and turmeric level drives the colour. Write down the colour you want and ask for a sample next to your current product.
How to protect your recipe
Your recipe is the asset. Before you send it, sign a confidentiality agreement and agree that the plant will not sell the same formula to others. In practice many buyers split the secret: the plant holds the full blend, and a key ingredient is sent as a pre-mix from a second source. See how to protect a blend recipe when working with a manufacturer for the options and their limits.
A contract is only part of protection. Limit how many people at the plant see the full sheet, and keep your own record of every approved sample code.
Approving the first batch
Approve against a signed pre-production sample, then test the first commercial lot. Check colour, aroma and particle size against the sample, and have a laboratory confirm moisture and microbiology. Natural spices vary from crop to crop, so agree in advance how much colour or flavour drift is acceptable and how the plant will adjust the recipe when a new crop arrives.
Cost depends on the ingredient mix, the grind and the pack, so we do not quote it here. A blend with a high share of costly spices, or one that needs roasting, will cost more than a simple one.
