Fact
Forever adds over 600 new crafting recipes across all professions and level ranges combined; no source found breaks this total down cleanly by profession for Cooking or Fishing specifically (one unverified SEO site, zockify, claims 44 new Cooking recipes and 3 new Fishing recipes, and separately that 'each profession gains three profession-specific campsite recipes').
