Funny I am making these tomorrow for a pot luck family reunion ...
I noticed you have been looking for the recipe for the bean dip they serve at the Century House in Peabody Ma, they also serve a similar one at the Hungry Traveler in Salisbury Ma. I grew up in Ipswich Ma. and have had the dip you speak of many, many times and it is indeed delicious, their recipe is grarded but fortunatly for me, (and now you), my father-in-law was a cheif and also made a similar dip. If you would like to try it here is his similar and also very delicious recipe. This is the smaller version.
1 - 16 oz can red KIDNEY BEANS, rinse drain and set aside
Place in a small bowl about 4 oz small curd COTTAGE CHEESE, whisk up a bit to break up curds
About 2 TBS finely chopped RED ONION
1 small clove of GARLIC ... crushed & minced
About 2 TBS MAYONNAISE
Abour 2 TBS prepared HORSERADISH
A dash or two of TABASCO SAUCE
Mix well and toss with beans being careful not to break up beans. Serve with assorted crackers. This is the version he made for the resteraunt he helped to establish in Haverhill Ma, sorry I cannot name it, he is gone but the resteraunt thrives, also I believe the one at the Century House is a copy of his! This is a more or less recipe nothing is written in measurements, play with it a bit if you like. Better if made a day ahead.
