What is Scam Chowder?

Scam Chowder available June 30, 2015 Scam Chowder (Five-Ingredient Mystery #2) comes out this week. Here is a preview of the opening chapter from Val, the sleuth in the series.
Cook and run—those were Granddad’s instructions to me this evening. I was supposed to make the chowder for his dinner guests from the retirement village and get out of the kitchen. Then he would add the final ingredients and claim credit for the whole meal. This ruse was part of his campaign to win the heart of Lillian, the Village’s most attractive widow, whose husband had made her gourmet meals. To convince Lillian of his cooking skills, Granddad has no qualms about passing off my recipes and my dinners as his own creations. By eavesdropping, I discovered that more than a romance was at stake tonight. Granddad, egged on by Lillian, planned to confront a dinner guest who’d scammed retirees out of their savings. But someone beat him to it, making tonight’s chowder the last thing the scammer would eat.

Val makes two types of chowder for her grandfather's guests. When writing the book, I found a helpful video on cooking chowder: How to make three kinds of clam chowder, with Providence chef Michael Cimarusti. The 5-ingredient clear chowder meets Granddad's standards for a recipe. 
Which type do you prefer: clear chowder, red chowder, or creamy chowder?
