Why you have to boil pasta in hot water but rice in cold water

• Dried pasta can be boiled either in cold or warm water but hot water is easier for timing
  • There are two processes: hydration and gelatinization
    • ​Hydration is primarily for dry pasta​
      • ​once the hydrated starches reach a certain temperature they gelatinize
      • "gelatinization":Starch gelatinization is a process of breaking down the intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water.
    • " Mixing most starches in warm water produces a paste, such as wheatpaste, which can be used as a thickening, stiffening or gluing agent. "
• Rice can be cooked in either as well but putting in cold water is better
  • Simmer
