While smoked ham and beef are great, are there alternative ingredients that can still impart the 'smoked' flavoring?
If you want to remove the meat completely, many "meat replacements" like tempeh and tofu are available in smoked varieties. Most of these simply have liquid smoke AKA "Natural Smoke Flavoring" added as part of their process, but actual smoked varieties do exist.
Smoky flavors can also be attained from the following
- Freshly roasted cumin
- Spanish style smoked paprika
- Chipotle or other smoked chiles
- Liquid Smoke
- Some porters, stouts, and especially rauchbiers
- Lapsang Souchong tea
- Smoked salt
- Katsuobushi/Bonito flakes (also adds a distinct fish flavor)
