Magma Gochujang

Traditional gochujang ferments gochugaru chili flakes with glutinous rice and soybeans. This version substitutes dehydrated, ground Magma tomato — creating a paste with the umami depth of Korean fermentation and the fruity heat of an engineered Solanaceae.

  • 2 cups water

Instructions

  1. 1

    Cook rice flour and water into a thick porridge. Cool to room temp.

  2. 2

    Transfer to a clay pot or glass jar. Cover with cheesecloth.

  4. 4

Tips

  • This is a long-term project. Mark your calendar.
  • Use as you would regular gochujang in any Korean recipe.
Science Note

Meju's Aspergillus and Bacillus cultures produce proteases that break down soy protein into glutamic acid (umami). Capsaicinoids from the Magma tomato are stable through the entire fermentation — they don't participate in microbial metabolism.
