I love to cook, but hate to measure ... so I pretty much guess at everything :) I've been a member of this site for a while now. I rarely rate or comment on a recipe unless I truly love it or have some constructive critique to offer. I've become quite disillusioned with how many people feel the need to post snarky or non-helpful reviews. I always read reviews and if I see something with a very low rating, it seems there is always a spiteful, off-topic review that's contributed. If you don't follow the directions and sub ingredients like mad, how in the world can you give a one-star review to the recipe?? Anyway, those are my thoughts, and here's another: We should be helpful to each other! That's what made this a wonderful community! :) As to that: d-e-f-i-n-i-t-e-l-y. Not defiantly, but definitely. Quite a difference there as far as definitions go. :) In addition: If the recipe calls for cilantro, but you don't have cilantro and decide to use oregano: You have NOT substituted cilantro for oregano. You have substituted oregano for cilantro. Marinade is a liquid mixture (usually vinegar, oil, and herbs) in which meat is soaked before cooking. Marinate is the corresponding verb (i.e., to soak in marinade).
