Whats there to say about a fantastic chocolate chip cookie! The only thing that could be improved is if they offered a bushel box of these so you would not run out so fast. Hope these don't go the way of the dinosaur!

This company is an American Classic been in business over 90 years. Why? Because it is the best hot sauce and taco sauce bar none. There are some other good brands oout there, but this is the best and nothing compares to it. The Hot sauce has reasonable heat and bite and adds unique flavor to your favorite Mex foods. The taco (Mild) sauce is milder and just perfect on tacos, enchaladas, tostadas, tamales, Bell Beefers, and frozen mex dinners. The harder to find green sauce is to die for. Great on everything! Unfortunately I don't see the green stuff on Amazon but you can find it. Just get it. Try all three. I grew up with this stuff so am very partial to it. I keep about five or six bottles (each variety) on my shelves at all times. After you try this you will not want to go back to the run of the mill commercial stuff.<a href="http://www.amazon.com/gp/product/B0000GGHZQ">Pico Pica Mexican Hot Sauce 7 oz - HOT</a><a href="http://www.amazon.com/gp/product/B0000GGI00">Pico Pica - MILD - Mexican Hot Sauce 7 oz</a><a href="http://www.amazon.com/gp/product/B0084D71ZM">Pico Pica Mexican Hot Sauce 7 oz - HOT(PACK OF 3)</a>
