Turun sinappi

Turun sinappi is a traditional mustard. The production of this mustard started in Turku in 1926, hence the name. It consists of finely ground mustard that's dark yellow in color, along with a variety of spices. There are four main types of the mustard – väkevä (strong), mieto (mild), tulinen (fiery), and linnan sinappi (mustard of the castle), with väkevä being the most popular type in the country.

In the early 2000s, the brand was bought by Unilever, but in 2014, the production of turun sinappi was moved back to Finland. The mustard is usually served as an accompaniment to sausages.
