Did Kayin offer up honey?

Question

I recall learning somewhere that Kayin's offering was honey, produced from fruit (dates or figs). What is the source for this approach?

Answer 1

According to this Parsha sheet, the source is the משך חכמה

לא קיבל מנחת קין כי היה דבש ואסור להקריב שאור ודבש, כי צריך משהו שמעורב בו מעשה אדם כסולת חיטים

Kayin's sacrifice was not accepted because it was from honey...
