Steps:

1. Prepare the shellfish stock using prawn heads and shells.
2. Pour the strained stock into the canisters of a culinary centrifuge; spin until the liquid clarifies into a pure essence.
3. Place butter, saffron, and lemongrass into a vacuum bag; use a chamber vacuum sealer to pull a full vacuum for precision infusion.
4. Set the immersion circulator to 125.6�F (52�C).
5. Clean prawns and place in a vacuum bag with the saffron-infused butter; seal and submerge in the water bath for 12�15 minutes.
6. Reduce the centrifuged shellfish essence with white wine, using a digital refractometer to verify the ideal density/sugar concentration.
7. Add lecithin or heavy cream to the reduction; pour into a siphon and charge with gas cartridges.
8. Remove prawns from the bath, pat dry, and give a brief singe with a culinary torch for aroma.
9. Plating: Place prawns in a shallow bowl, dispense saffron foam from the siphon over the top, and garnish with chervil.
