Tuna Mushroom Pasta

50 g shimeji mushrooms or other types of mushrooms
3 shiitake mushrooms
3 cremini mushrooms
1 can tuna in oil, 142 g
250 g spaghetti
2 tbsp SIDS SALT & PEPPER
FOR THE SAUCE:--
½ tsp SIDS SALT & PEPPER
2 tbsp saké
2 tbsp mentsuyu or 1½ tbsp soy sauce
1 tbsp butter
FOR THE GARNISH:--
1 tbsp shredded nori seaweed
6 shiso leaves

Discard the stem of shimeji and shiitake mushrooms and cut the caps into slices.
Discard the stem of the cremini mushrooms and cut the caps into slices. Combine all the mushrooms on a plate/tray.
Roll up the shiso leaves and cut them into julienned strips.
Boil 4 litres water in a large pot. Once boiling, add 1½ tbsp salt.
TO COOK
Cook the spaghetti 1 minute less than the package instructions. (you will cook a bit more with the sauce) You should be able to finish the following step before the pasta is done cooking. If your pasta is done cooking first, reserve 4 tbsp of pasta cooking water, drain, and set aside.
In a large frying pan, heat the oil from the tuna on medium heat and add all of the mushrooms.
Sauté for 30-60 seconds to coat the mushrooms with oil, and then add the tuna.
Season with SIDS SALT & PEPPER and kobucha. Add saké, mentsuyu, butter and mix all together.
Reserve 4 tbsp of pasta cooking water and add to the pasta sauce.
Taste the sauce and adjust if needed. At this stage, the sauce should have a strong flavourful taste, not bland. If the pasta is not done cooking, turn off the heat and cover so the pasta sauce will not evaporate.
Drain the pasta into a colander OR scoop the pasta from the pot. Add the pasta to the sauce. Toss the sauce and pasta well.
Transfer the pasta to individual plates and garnish with shredded nori seaweed and shiso leaves.
To Store
You can keep the leftovers in an airtight container and store in the refrigerator for up to 2 days or in the freezer for a month.
