Question
What was the exact amount and what were the detailed sacrifices Cain and Adam brought?
Answer
ב"ה
Shalom
The information we have from the Midrashim and Rashi is only that Able brought from the finest of his firstborn sheep, while Cain brought the most inferior quality produce from his field. There is an opinion in Midrash Tanchuma which Rashi quotes that Cain brought flax seeds.
All the Best
