Make sure you buy young green jackfruit in water or brine, not sweetened jackfruit. You can find it in 20-ounce cans in Asian grocery stores for about $1.50 per can. I find that a 20-ounce can yields 10 ounces of jackfruit once it is drained.
Brands of jackfruit vary. Some can contain pieces that are tougher than others and may require additional cooking time or even chopping with a knife. Of the brands I've tried, I have found Chaokoh
to have the most tender jackfruit.
