Especially in winter, you may notice small white spheres forming in the powder. This is simply the coconut milk solidifying due to the cold. The coconut milk powder we use is extremely pure and contains 65% fat (coconut oil). When temperatures drop, the coconut oil solidifies, causing small lumps to form in the mix. No worries! They will melt upon contact with boiling water, as coconut oil turns liquid above 24°C (75°F).
