I would recommend rehydrating your yeast really quick before pitching. To do this, simply put 1 cup of lukewarm (90F) water in a sanitized bowl and sprinkle the yeast on top. Let that sit for about 15 minutes and then pour it all into your batch and stir.
If you don't want to do that, you can still sprinkle it on top. You can stir if you'd like, just make sure the spoon is sanitized.
