Blackened Fish Tacos with Lime Slaw

• Slaw
• 3 cups green cabbage, thinly sliced
• ¼ cup fresh cilantro, chopped
  Swaps for fresh cilantro

  Instead of cilantro

  • Dried cilantro: 1 tsp dried for each 1 tbsp chopped fresh (a third as much). Dried cilantro has almost no flavor; skip it as a garnish and add more of the other seasonings.
  • Flat-leaf parsley + lime zest: The same amount of parsley, plus a little lime zest. Fresh and green, without the soapy taste some people get from cilantro.
  • Thai basil or mint: Half as much. Sweeter and more perfumed.

  More for cilantro

• 2 tbsp lime juice
  Swaps for lime juice

  Instead of lime juice

  • Lemon juice: The same amount. Milder aroma; still bright.
  • Bottled lime juice: The same amount. Flatter and more sour; fine in cooked dishes.
  • Rice vinegar or white vinegar: Half as much. Sour without the citrus aroma.

  More for lime juice

• 1 tbsp olive oil
  Swaps for olive oil

  Instead of olive oil

  • Avocado oil or another neutral oil: The same amount. No olive flavor; avocado oil handles higher heat.
  • Butter: The same amount. Richer and nutty when browned.
  • A neutral oil + more seasoning: The same amount. Dressings lose the fruity, peppery note; a little extra lemon, garlic or mustard makes up for it.

  More for olive oil

• ¼ tsp kosher salt
  Swaps for kosher salt

  Instead of salt

  • Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
  • Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.

  More for salt

• ⅓ cup mayonnaise ≈ 73 g

• 2 tsp smoked paprika

• 1 tsp garlic powder
  Swaps for garlic powder

  Instead of garlic

  • Fresh garlic: 1 clove for each ⅛ tsp powder, minced fine. Sharper and stronger.

  More for garlic

• ½ tsp onion powder
• ½ tsp dried oregano
  Swaps for dried oregano

  Instead of oregano

  • Fresh oregano: 1 tbsp chopped fresh for each 1 tsp dried (three times as much). Brighter and more peppery; use a little less than you think.
