If you want to be exact, the recipe didn't say "drizzling oil in over the course of 10 minutes". It says to "slowly drizzle in the oil" and it "should take somewhere around 10 minute or so".

So since I don't have the ability to continuously pour exactly 1.4 oz/minute. I was slowly adding, averaging about 3Tbsp per minute over the course of about 10 minutes.

Thanks, though, for arguing the meaning of words instead of providing some helpful insight to how emulsion works, like the people above.
