Steam 150g of pumpkin or butternut squash, chopped into chunks and a handful of gingko nuts for 15 minutes.
After the butternut squash has softened after steaming, use the back of a fork to mash the squash until it looks slightly pasty.
Add 2 handfuls of ikan bilis and 1 handful of dried shrimp, followed by 300g of fish bones, preferably Garoupa as they make the best tasting fish broths.
We are using the much more premium Barilla bronze dye spaghetti here. It has a rougher texture and is able to absorb sauces even better than the regular pasta.
