Cut the guavas and remove the seeds.
Soak the seeds in water.
Place the guava pieces in a saucepan with the rest of the water.
Bring the water to a boil and let it simmer.
Cook until the guava is soft.
Strain the water from the seeds and mix the liquid with the guavas.
Use a food processor to grind the guavas and add the sugar.
Place the new mix in a saucepan over low heat.
Keep on stirring until the mixture is thick.
Remove from heat and stir with a wooden spoon until the paste is cold and thick.
Line a baking sheet with wax paper and let the paste cool for a day.
Store the paste by rolling it in foil paper until it’s needed.
