Step 4.) Transfer your beef slices (or slabs) to a bowl / dish and combine with spices and vinegar. I prefer freshly toasted coriander seed (biltong staple known for antimicrobial properties that help inhibit the growth of bacteria and mold), red chili powder, brown sugar, and obviously a good bit of salt. *This about 1.2lbs of beef and I used roughly 4tbls of vinegar, 2.5tbls of salt, 2-2.5tbls of red chili powder, 1.5tbls of coriander, 1tbls brown sugar. Nothing needs to be perfect here, just cater to your preferences.
