| The fundamentals of mustard manufacture are still broadly
similar to those used by Jeremiah Colman over 170 years ago. Nothing is left
to chance these days, though, Colman's have been carrying out experiments
in plant breeding since 1946 which have produced crops that are ideally suited
to modern methods of cultivation and give outstanding results.
At Carrow the seed still undergoes thorough sampling, cleaning, and drying processes to ensure it reaches the mill in excellent condition. A giant silo holding nearly 10,000 tons stores the seed until needed. In the mill the seed is crushed in break rolls, (the husk removed), seived in purifiers, and gradually reduced to a fine powder with frequent siftings. Nowadays, as many people prefer to buy their mustard ready-made, a large part of the building is devoted to the manufacture and packing of various types of prepared mustards. |
