For the octopus: Place the octopus
in a pot large enough to fit comfortably and then add the vinegar, peppercorns, garlic, bay and onions
. Add enough water to cover and bring to a boil over medium-high heat. Immediately reduce to a slow simmer and skim
off any foam
from the surface with a ladle. Simmer
until the octopus is knife-tender, 45 minutes to 1 hour. Remove from the heat and let cool to room temperature in the pot with the liquid.
For the tandoori marinade: Combine the yogurt, garlic and ginger in a bowl and let sit for 15 minutes to mellow the raw garlic.
Meanwhile, heat a dry skillet over medium heat and add the paprika
, peppercorns, coriander
, cumin, turmeric, allspice and cardamom
and toast until aromatic
, turning the pan frequently to avoid burning.
Stir the toasted spices
into the yogurt mixture and let sit so the flavors can come together, 10 minutes. Separate half of the tandoori marinade
For cooking the octopus: Remove the octopus from the liquid, add to the remaining tandoori marinade and refrigerate until ready to grill.
Preheat the grill
to 500 degrees F.
Sprinkle the octopus with salt and grill on the lowest rack until crispy at the ends and the flesh is heated through. Transfer to a cutting board and cut the large tentacles into individual pieces, and then in half crosswise. The smaller tentacles can be left whole. Scatter on a plate and top with the Fennel Slaw in a row down the middle. Garnish with grapefruit
, lime wedges, sea salt
and the remaining tandoori marinade.
