I have a Latin American recipe that calls for grated coconut in heavy syrup. Apparently, you can commonly buy it in cans in Latin America, but not here in the USA. Can I substitute some mixture of dry coconut and syrup? What kind of syrup, in what ratio?  I have some sweetened dry coconut and light corn syrup on hand; if there's a way to make it work with those, that would be great, but if not that's OK too :) 
As a Latin American, we usually use fresh grated coconut, water and sugar to make this type of filling for sweets. If fresh grated coconut is not available, desiccated grated coconut is fine, we just adjust the amount of water when making the filling to reach the desired consistency This recipe for the sweet calls for 150g of desiccated coconut for 2 cups of sugar and 2 cups of water. 1 cup is typically 240mL, or 8 fl. oz.
