Grind half of each of the two types of mustard seed in the coffee grinder to a fine powder.
Then grind the chipotle chillies to powder as well. Of course, other types of chilli can also be used, but the taste will vary a lot because of the smoky aroma of chipotle chillies!
In a saucepan, mix the honey with the apple cider vinegar, the oil, the remaining mustard seeds and the 3 powders and reduce over a medium heat until a thick, creamy mixture is formed.
Then fill the mass into screw-top jars.
Tastes great with grilled food, on bread (both with sausage and cheese) and actually with almost everything if I have my way!
