Add sausages, raw, to slow cooker and top with onion and mushroom

Combine stock, water, paprika, garlic, Worcestershire and pour over

Cook on low for approx. 4hrs

You may like to cut your sausages at this point into slices and return to pot, or leave whole if you wish. I like to cut mine.

Add the combined sour cream and cornflour and mix well to combine

Continue to cook for an additional 10-15 minutes to heat through and thicken.

Serve on pasta or with rice and steamed green veg
