Take something meaty, like a chicken soup. Add a pinch of salt, and taste it. Add another pinch of salt, and taste it again. You'll notice how the flavors become deeper and more complex – then suddenly, you'll go one step too far, and the saltiness will ruin the soup.\n\n![Graph](image://fc357847-178c-459f-8992-7370d3219d5b \" \")","8e0d92b5-ae9b-4985-be2c-974fd64d959a",{"id":63,"data":64,"type":33,"maxContentLevel":19,"version":33,"reviews":67},"6d775492-e006-49f4-a3ce-fb61fb861992",{"type":33,"markdownContent":65,"audioMediaId":66},"If you're salting meat, you'll want to do it nice and early.

This liquid can be used as a cooking medium, just like oil. If you're frying vegetables or even a piece of meat, rendered fat will result in a stronger, meatier taste than you'd get with a plant-based oil.\n\nOf course, you won't always want a meatier taste.

Acids are polar, while fats are non-polar, meaning they repel each other instead of forming a stable mixture.\n\n![Graph](image://5dc9742b-5982-47a7-b317-5afd1f2f8097 \" \")\n\nBut this problem can be solved by adding an **emulsifier** – that's a third ingredient whose molecules act as a connective bridge between molecules of acid and molecules of fat/oil.\n\nPopular emulsifiers include lecithin (found in egg yolk) and mucilage (found in mustard). If you're mixing vinegar and olive oil to make a vinaigrette, try adding a spoonful of mustard. Suddenly, you'll find that the acid and oil stop splitting.\n\n![Graph](image://2cecf0a5-3ca1-4f4c-8400-69a8bc8ed933 \" \")","78a02704-0712-4104-8104-a3f1619c9ff7",[286,303,312],{"id":287,"data":288,"type":51,"version":33,"maxContentLevel":19},"fabfae05-3d6a-4a0d-a14b-076bfb718d16",{"type":51,"evolvingBehavior":113,"spacingBehaviour":33,"matchPairsQuestion":289,"matchPairsPairs":290,"matchPairsShowExamples":6},[234],[291,294,297,300],{"left":292,"right":293,"direction":20},"Acid molecules","Polar",{"left":295,"right":296,"direction":20},"Fat and oil molecules","Non-polar",{"left":298,"right":299,"direction":20},"Emulsifier in egg yolks","Lecithin",{"left":301,"right":302,"direction":20},"Emulsifier in mustard","Mucilage",{"id":304,"data":305,"type":51,"version":33,"maxContentLevel":19},"089fad57-7c3b-4500-bd10-00e3864520f4",{"type":51,"evolvingBehavior":20,"spacingBehaviour":33,"multiChoiceQuestion":306,"multiChoiceCorrect":308,"multiChoiceIncorrect":310,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6},[307],"If a dish ever feels dry, what might improve the texture?",[309],"Fats and oils",[26,311,89],"Acid",{"id":313,"data":314,"type":51,"version":33,"maxContentLevel":19},"117e053d-e49a-4fac-89bc-1b4fdf7e36fc",{"type":51,"evolvingBehavior":20,"spacingBehaviour":33,"multiChoiceQuestion":315,"multiChoiceCorrect":317,"multiChoiceIncorrect":319,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6},[316],"What process allows you to turn solid fat into a tasty, oil-like liquid?",[318],"Rendering",[195,320,321],"Denaturing","Blending",[323,483,648],{"id":23,"data":24,"type":25,"version":20,"maxContentLevel":19,"summaryPage":27,"introPage":34,"pages":324},[325,370,407,453],{"id":43,"data":44,"type":33,"maxContentLevel":19,"version":33,"reviews":47,"parsed":326},{"data":327,"body":330,"toc":368},{"title":328,"description":329},"","When we talk about salt, we're really talking about tiny crystals of a mineral called sodium chloride.
