Vietnamese Lemongrass Chicken

Variations

• Rice bowl (com): Serve over rice, com-ga-nuong style.

Tips

• Mince only the tender white base of the lemongrass so it isn't fibrous.
• Fish sauce is the backbone of the flavor — don't hold back.
• Stir-fry over high heat so the chicken sears instead of steaming.
• Use half in the marinade, half in the pan for double the aroma.
• Most dishes take the aroma and throw the lemongrass away. This one eats it. In tom yum, rendang, laksa and fish amok the stalk is bruised, or blended, or dropped in whole and fished out — because lemongrass is a grass, and its cellulose does not soften however long it cooks. Time will not fix a coarse mince. That is the real reason for taking only the tender white base and cutting it as fine as you can manage: you are not seasoning a broth you will strain, you are putting it in your mouth.
• The "double aroma" tip has a mechanism. Lemongrass smells of citral, the same aldehyde family that makes lemon peel smell of lemon, and it is both fat-soluble and volatile. The half in the marinade goes in with oil and then spends minutes over high heat, which rounds it out and loses the top notes; the half fried at the start and met again by a sauce that only reduces "slightly" keeps them. Same ingredient, twice, at two different distances from the heat (blooming spices).
• The fish sauce is the salt, which is why twenty minutes is enough. What marinades do is clear that aroma stays on the surface and salt is the one thing that travels; fish sauce is heavily salted, so it seasons the meat in the time it takes to mince the aromatics. It is also worth not boiling it hard at the end — its savour sits in volatile compounds that a long reduction flattens into plain salt.
• Set beside satay. Both are Southeast Asian marinated chicken with a sweet-salty seasoning, and they part company over where the sauce is: satay grills the meat dry and pours the sauce over afterwards, this one reduces its sauce onto the chicken in the pan. One dish keeps them apart; the other joins them.
