When I was a little girl I would visit my grandaunt in Melaka during my school holidays. My grandaunt and my grandmother would make batches and batches of homemade fishball for the family to eat together. It was a long and tedious process because they did everything by hand. Scrapping the fish using spoons and used cleavers to chop up the fish to a fine paste. Having so many mouths to feed they would spend a good portion of the morning, scrapping, pounding, chopping and seasoning the fish paste. They would cook it in a broth of salty water and serve it with fresh pulled noodles. Drizzled with toasty sesame oil and some greens it was one of the highlights of a family meal. But now we have blenders and other tools and gadgets to help us make a wholesome meal for our love ones so there are no excuses!
Another alternative is to make the paste and stuff it into vegetables making your own Young Tau Foo. A great way to control what you eat at home is to cook your own meals from scratch. If you wish to substitute the fish with prawns you may or combine some ginger and garlic.
