    If you choose CSS styled icons in the Theme Customizer total of 10KB or 11KB

    – 1 CSS file of 2KB (the basic CSS style) or 1 CSS file of 3KB (the default CSS style), depending on your choice.
    – 2KB of embeded in head styles for the CSS icons.
    – 1 JavaScript file of 6KB.

    If you choose in the Theme Customizer to use Ionicons icons and Google webfont Roboto: around 75KB – 76KB

  • Externally loaded styles and scripts on the front-end (You can disable them in the Theme Customizer):
    – Ionicons (ionicons.min.css – 51KB) – loaded externally from CDN (MaxCDN). Used for the styling of (+) plus and (-) minus buttons, and for the (✓) check mark, added when you click on an ingredient to mark it as added.
    – 1KB of embedded JavaScript code in footer, that loads Google webfont Roboto at weights 300,400,900 for display of all text of Ingredients and Instructions. This loads webfont.js from Google CDN, which is 12.8KB and some CSS styling.

Adding Ingredients

For each ingredient you can choose a Measurment unit – ml, L, kg, g, etc. If your ingredient doesn’t have measurment unit (e.g. onion, chicken fillet) – there is option “None”.

If you select “None” option another field will appear where you have to add the plural name of your ingredient. (e.g. Ingredient name is onion –  Ingredient Plural name – onions).

Recipe Calculator Plugin

Since version 1.0.7 you can select “empty” option below Measurement unit. Then you can add just an ingredient, without having to specify quantity – for example Salt, Pepper, etc.

Splitting the ingredients:

Since version 1.0.3, below Ingredients at the admin area, you have an option to add text(s) that will split the ingredients into groups. This can be useful if your recipe contains sauce or filling and you want to separate their ingredients from the main dish ingredients.

In this meta box 1st you add the text to be shown e.g. Ingerdients for the Sauce and then in the metabox next to it you can specify before which Ingredient Number this text should be inserted. The Ingredient Number is displayed at the top of each ingredient that you add.

If you don’t need to split your ingredients, just leave these metaboxes empty.

Adding Nutrients

Since version 1.0.7 you can add nutrients for each recipe. To set all nutrients you want to be shown, you can add them via Settings-> Recipe Calculator screen in Admin area. Once added nutrients will be recalculated per portion as well.

If you enter a number less than 1 and measurement unit is “g” or “гр” in Bulgarian and Russian language, value will be multiplied by 1000 and measurement unit will be automatically changed to “mg” or “мг” in Bulgarian and Russian. As the number of portions increase, once the value reach more than 1000 milligrams, it will be automatically changed to grams and diversed by 1000 and vise versa. See below picture:
