Soy Milk Tarako Spaghetti

Tonight's dinner was a variation on the mentaiko spaghetti that I made before - today I used tarako (salted roe), and instead of just mashing it up and mixing it with butter and the pasta, I also added a soy milk broth for creaminess and some boiled and diced potatoes for volume. H and I had a split vote on which pasta we liked better - H liked the spiciness and saltiness of the mentaiko spaghetti, while I liked the mild sweetness and creaminess that the soy milk added to the tarako spaghetti.
