A shiddukh "test" also apparently making the rounds involves pantry inspection. It's one thing to judge someone by the hechsherim they use, but something almost surreal to put emphasis on how much poor-quality food people will purchase.
How this works...
[Buying Israeli like Osem or Elite does not count as "hamische", by the way.]
Choose the brand you would more likely purchase in the store (if given a choice)

Ketchup Heinz/Hunt's Gefen
Mayonnaise Hellman's/Best Foods Unger's
Sandwich Cookies Oreo's Bloomy's
Salad Dressing Ken's Steak House Haddar
Microwave Popcorn Orville Redenbacher Mishpachah
Soy Sauce Kikkoman's Season
Cheddar Cheese Tillamook Miller's
Butter Land o' Lakes Morning Select
Pasta Sauce Barilla Mrs. Adler's
Potato Chips Lay's/Ruffles Lieber's
Results:
If you selected Column A, you are not "frum enough" since you give money to goyishe companies. (You should be ashamed of yourselves for daring to buy better quality food.) [However, if you have sons the same age as my daughters, let's talk shiddukh in 20 years! They are beauties, b'li ayin ha-ra and both want to be doctors, so they're smart as well.]
If you selected Column B, you feel you have something to prove to your neighbors. Even if a lot of these companies are goyishe, they cared enough about the kosher consumer to make tasty food accessible to us.
