Two types of thickeners using fat and flour are a beurre manie or a roux. Thickening with flour and fat give sauces and gravies a smoother texture than thickening with flour and water, and a beurre manie has a smooth, rich taste. Mix together 4 tablespoons (32 g) each of all-purpose flour and room temperature, softened butter in a small bowl. Use a fork to mash together the flour and butter until they form a paste. Form this paste into small, tablespoon sized balls for easy use. If you don't need to use them right away, freeze these balls in an airtight container, and bring them to room temperature before use. The sauce should be almost finished cooking, as you don't want the beurre manie to cook for too long. Whisk it into your sauce thoroughly, and allow the sauce to simmer for an additional minute or two before taking it off of the heat. This will ensure the taste of your sauce is smooth, without any residual starchy flavor from the flour. A roux is an excellent way to make thick stews, gravy, gumbo, or cheese sauce. Use two tablespoons (16 g) of butter and all-purpose flour. Roux also uses an equal ratio of flour to butter. Cooking the flour in the butter will help remove the pasty taste of the flour. Heat the butter over medium heat in a saucepan, until it's melted. Add just a little bit of oil to the pan to keep the butter from burning. Once the butter has melted, gradually add in the flour, whisking constantly until it's combined and smooth. At this stage, decide how dark you want your roux to be. A darker roux has a darker brown coloring and a nuttier flavor. For a dark roux, continue cooking and stirring constantly until you start to smell a nutty aroma, and your roux is a caramel color. Take your roux off the heat. Gradually whisk your roux into your sauce. Cook the sauce over medium to medium-low heat for 30 minutes or more, stirring occasionally with a spoon or whisk, to give it a smooth, velvety texture. Some bubbling is fine, but do not keep the sauce at a boil. Though butter often works best, you can use a combination of other fats and flour to create a similar thickening effect. For gravies or stews, consider using meat drippings instead of butter. If you want a vegan option, you can use a plant-based oil, like olive oil, or a premade vegan butter in place of butter.

Summary: Make a beurre manie. Add your beurre manie to a sauce. Create a roux. Use an alternative to butter.

If you have a PS3 for which you would normally use your controller, turn it off and unplug it to prevent accidentally turning it on while you pair the controller with your Mac. Using a bent paperclip, press the recessed Reset button that's on the bottom of your controller. This will prevent the controller from running into issues left over from previous pairings. This step is optional, but highly recommended. Click the Apple logo in the top-left corner of the screen. A drop-down menu will appear. It's in the drop-down menu. This will open the System Preferences window. It's the Bluetooth icon {"smallUrl":"https:\/\/www.wikihow.com\/images\/9\/9c\/Macbluetooth1.png","bigUrl":"\/images\/thumb\/9\/9c\/Macbluetooth1.png\/15px-Macbluetooth1.png","smallWidth":460,"smallHeight":920,"bigWidth":"15","bigHeight":"30","licensing":"<div class="mw-parser-output"><p>I edited this screenshot of a Mac icon

Doing so enables your Mac's Bluetooth. If this button reads Turn Bluetooth Off instead, Bluetooth is already enabled. Attach the small end of the charger cable that came with your PS3 controller to the controller's charging port, then plug the other end into your Mac's USB port. If your Mac uses USB-C ports (ovals) instead of USB 3.0 ports (rectangles), you'll need to buy a USB 3.0 to USB-C adapter for your Mac before you can do this. You can find them on Amazon and in tech department stores. If the controller hasn't been charged for a while, you may want to let it charge for about 30 minutes before proceeding with setting up the Bluetooth connection. It's in the middle of the controller. Doing so will prompt the lights on the top of the controller to begin flashing. The PS3 controller will appear in the list as "Connected" after a few seconds. If your Mac prompts you for the device's passcode, type 0000 and then click Pair. This usually isn't required on newer Macs. Now that the PS3 controller is connected to your computer via Bluetooth, you can use it in any game that supports gamepads. You may have to manually set the controller buttons for game functions; this varies from game to game.
Summary: Power down and unplug your PS3. Reset your controller. Open the Apple menu . Click System Preferences. Click Bluetooth. Click Turn Bluetooth On. Connect the PS3 controller to your Mac. Let the controller charge if necessary. Press and hold the PlayStation button for 2 seconds. Unplug the controller and wait for it to sync. Enter 0000 as the passcode if prompted. Set up your controller in-game. Finished.
