Prep Jackfruit: Drain excess moisture from canned jackfruit. Pulse in a food processor until shredded but not paste-like.
Mix: Add dry ingredients (salt, nutritional yeast, vital wheat gluten, pea protein, gram flour, garlic and onion granules, vegetable stock powder, optional MSG) to the food processor and pulse to combine. Knead mixture by hand for 5 minutes, then let rest for 30 minutes to as long as you have.
Make Spice Mix: Grind spice mix ingredients together while the jackfruit rests.
Prep Dredges: Combine flour, corn flour, and spice mix for the dry dredge. Whisk plant milk, apple cider vinegar, and some dry dredge for the wet dredge.
Shape & Coat: Form jackfruit mixture into 3 patties. Dredge each in dry dredge, wet dredge, then dry dredge again, pressing to create a craggy coating.
Deep Fry: Heat oil to 190°C (375°F). Fry patties for 10 minutes, or until golden brown, turning occasionally. Drain and season with salt. Serve in buns with your favourite toppings.
