Ex Input:
This is my 4th Six Sisters Stuff cookbook and this one is easily my least favorite. The recipes seem so heavy - lots of frying, lots of high calorie/fat ingredients (cheese, pasta, cream). Actually, I love the dessert section in this book but probably for the same reason why I don't like the main dishes section (high caloric, high fat = yum!) My favorite of their cookbooks that I go back to lots is their "A Year With SSS".

Ex Input:
These were easy to install and seem to be of decent quality. The finish looks good with all my different door styles and colors. I really wanted all my doors to be keyed alike, and this set provided that option. In fact, each set came with four keys, so I have plenty of spares.

I've been using olive oil. I really need a good distributor. it's very good and unclear, so it can protect the oil from light. This dispenser is excellent and of good quality. The dumper did a good job and no oil dripped out.
