I love making ice cream. My Cuisinart ICE-30 BC ice cream maker is awesome. It's very easy too. You make a custard base out of heavy cream and egg yolk, let it chill for a while then pour it in a "freezer bowl" which sits in your freezer over night. This bowl sits on the ice cream maker's base and turns. The custard thickens in to ice cream as it is mixed by a paddle and hits the frozen walls of the bowl. You can make a million different flavors, you can even make them up. I recommend coffee ice cream for Father's Day. The better the quality of coffee beans, the richer the flavor.
Australian licorice is the best. It's thick and chewy comes in all flavors, anything from green apple, pineapple, peach to black. You can find it online or in many candy stores and even in large supermarkets like Super Wal-Mart here in the US. Key lime cheesecake is to die for, it's a big hit here in Florida, especially in Southern Florida. Key limes are much tarter than regular limes, the citrus flavor is much more concentrated. The fruits are smaller, about the size of golf ball. Garnish it with a fresh mint leaf. You can make no bake cheesecake, which is easier and tasty, but baked cheesecake in my opinion is better. Baked cheesecake is creamy and thick, no bake is just simply cream cheese. For thicker cheesecakes you can use a springform pan which has a bottom thin tray where the crust and filling go which fits inside a collar or belt-like metal loop that unbuckles after you undo the clasp once the cake is baked and has cooled. This loop loosens and widens as you remove it from the cake. This unbuckling prevents damage to the side of the dessert.
Biscotti is one of my favorite treats to make. Your whole house will fill with a fabulous nut, chocolate (depending on the recipe) aroma. Tossing them in a decorative coffee mug and complementing it with the coffee adds a special touch to it. I personally prefer this gift as the best choice on the list. Biscotti just means twice baked. You form the thick dough into 2 loaves, flatten it, bake it until it browns on the inside but remains uncooked on the inside, cut the loaves into long, finger-shaped pieces and bake them again. After cooling they come out crunchy and rich with flavor. Perfect for dipping in hot chocolate or coffee.
