Hello there. That is a wonderful memory, and recreating that pristine, glass-clear broth from childhood is a deeply rewarding culinary goal.
The main reason meat broth turns cloudy comes down to agitation and temperature. When meat and bones are brought to a rolling boil or cooked under pressure, soluble proteins coagulate into tiny floating fragments, while melted fats get mechanically beaten into the water. This creates an emulsion, which causes that murky, milky appearance. Modern multicookers often use intense heating cycles that boil the liquid too vigorously inside, which unfortunately guarantees a cloudy broth.
To achieve a completely crystal-clear liquid, you need to prevent that emulsion from forming. Here is the traditional technique that will give you that transparent, aromatic result:
1. Blanch the meat and bones beforehand. Place your raw meat into a pot, cover with cold water, and bring it to a boil for about 5 minutes. You will see a thick, grey foam gather on the surface. Drain everything into the sink, discard that blanching water, and thoroughly rinse the meat under cool tap water to remove any clinging residue. Rinse the pot as well.
2. Always start with cold water. Put the clean meat back into the pot and cover it with fresh cold water. A cold start ensures that remaining impurities release slowly and rise to the surface rather than seizing up immediately.
3. Maintain a gentle, lazy simmer. Bring the water up to heat slowly, and keep the temperature strictly between 85 and 90 degrees Celsius (185 to 195 degrees Fahrenheit). You should only see an occasional small bubble break the surface. If you are using your multicooker, select a low slow-cook mode that never reaches a rolling boil.
4. Never stir or shake the pot. Stirring breaks apart coagulated proteins and mixes fat back into the liquid. Let it sit undisturbed, gently skimming any foam that rises during the initial hour.
5. Strain through a fine filter. When cooking is complete, carefully remove the meat with tongs instead of dumping the pot. Strain the remaining liquid through a fine-mesh sieve lined with cheesecloth or a paper towel.
Following these simple steps will preserve the clarity and give you the beautiful, clean broth you remember from your rainy childhood evenings.
