Maybe you could helpfully specify what it is that you "want" in a date so your friend'll have some other brief than presumably just "nice/cute" and'll therefore be a little less obnoxious in introducing you to any random guy for having to make sure he fits your 'criteria.'
If you've tried this already, and she's still doing the same crap; then it means she doesn't respect your conclusions as to what it is you 'want.'
Just say something like "I appreciate the effort you go through, but it's making me feel awkward and pressured more than it's working." Point out how
her way of approaching it hasn't worked out for you, and maybe reference that quote about the definition of insanity.
Maybe you should say something about why you don't just fall in love with just anyone. That you're introverted, perhaps a little shy -- and
certainly shy when your friend suddenly draws
all the attention directly to you -- and want to know that someone is worth opening yourself up to through gradually getting to know their personality.
haha, yeah, my friend means well, but she doesn't quite understand that people don't like being matched to other people according to her tastes.
Emphasise the point, then.
Say that she's not respecting what your tastes are, and that's why it's not working.
She's your friend and is concerned enough about you to make a fool of herself in front of strangers (either that or if she's one of the people spoken about earlier in the thread as
@Jebediah mentioned; she's just a fool), so she can take a short smack on the nose and correction in your ways; because ultimately she's doing this for you, and if you emphasise how it's not going to work enough that she can't just wave it away and think "oh that's just her being silly," she'll respect what you say.
Also your status is "dating", so I worked on the assumption that you
do want to meet someone and it's just the manner of this 'strategy' that is bugging you.
