  • do it again but drink milk after.
  • #
First test I will rate that a 10/10
second test 5.3/10 with water
third test with milk 2.5/10

Many milk-based products contain a protein called casein, which can help break down those capsaicin tricksters. Think of casein as a detergent — attracting, surrounding and helping wash away the oil-based capsaicin molecules floating around your mouth, similar to how soap washes away grease.
