Berry Manor Inn Pie Moms throwdown on who's recipe is best (Courtesy PJ Walter, LimeRock Inn)

Did you know that Jan. 23 is National Pie Day? We didn't either, but thank goodness the Historic Inns of Rockland, Maine, are on top of these things. To celebrate, four coastal inns are hosting Pies on Parade this Sunday.

Each inn will be receiving ticketed guests between 1 and 4 p.m., with tours of common areas and some guests rooms. Taste various pies, from traditionals like cherry and apple to more modern variations like Key Limerock Pie, Seafood with Lobster Pie, Kiwi Berry Tart, and a Goat Cheese Breakfast Pie. Then take home a recipe collection so you can bake your own.

The four inns (the Berry Manor Inn, the Lindsey House Inn, the LimeRock Inn, and the Old Granite Inn) are within walking distance of each other. But a trolley will make the rounds. Some of Rockland's local businesses are also offering samples, including a Chocolate Decadence Pie at the Pastry Garden and Lemon Curd Pie with Ginger Crust at Lily Bistro. (Cue the drooling).

All proceeds go to the local Area Interfaith Outreach Food Pantry. And you can rest assured that the decadence won't hurt the environment: All of the pie will be served with biodegradable, "compostable" plates and silverware-made of sugar cane.

There are still some accommodations left at the inns, if you want to make a weekend of it; packages start at $160.

Tickets are $20 for adults, $10 for children 10 and under, and can be purchased by calling 877/762-4667. Rockland is about 90 minutes north of Portland, Maine.
